Police Radar FAQs

Stationary mode is useful if you want to scan traffic while parked on the side of the road. This technology has been used since police radar was invented.

 

Moving mode is used to monitor traffic speeds while the patrol car is moving. This is a more advanced technology, as the radar has to be able to figure out how fast the patrol vehicle is moving, and then figure out how fast or slow other vehicles are moving relative to the patrol vehicle speed.

 

All of Stalker Radar’s dash mounted radar systems and also the Stalker II MDR hand-held police radar gun include both stationary and moving modes standard.

What is Directional Radar?

Directional radar technology allows the patrol officer to measure the speeds of vehicles moving towards the radar or away from it, or even monitor both directions simultaneously. By allowing you to choose which mode you are using at any given time, Stalker Radar products allows for more precise and accurate targeting.

Can Radar Work in Rain? Snow?

Precipitation in any form (rain, hail, sleet, and snow) can reduce the distance at which vehicles can be detected, but it does not affect the accuracy of the readings themselves.

Does Radar Work at Night?

Yes. Radar is not dependent on light at all, and so it offers the same accuracy whether used at night or during daylight hours.

What is the Difference Between K-Band and Ka-Band Radar?

The difference between K- and Ka-Band radar comes down to the frequency of the signal. Technically, the K-band frequency is 24.150 GHz, and Ka-Band ranges from 33.4-36.0 GHz. Because the frequency of Ka-Band radar is higher, the antenna that pick up those signals can be smaller.

How Police Radar Works, How To Avoid It With The Best Radar Detector

Radar’s exceptional versatility makes it a favorite of traffic officers.

Police radar transmits radio waves at a fixed frequency. Some of the beam reflects from a target vehicle and returns to the radar. If the target is moving, a slight change in frequency occurs (Doppler shift). The radar does the heavy math and calculates target speed.

How Police Radar is Used

Two types of radar are used—stationary and moving. Stationary radar must be used from a static site, typically a patrol car parked at roadside, sometimes a motorcycle. The most common type of stationary-mode radar is the hand-held model that looks like an oversized pistol.

Moving radar allows an officer to clock vehicles while driving on patrol. It can clock oncoming vehicles and if it has dual antennas, a departing car can also be clocked from behind, after it’s passed the rolling cruiser.

Most moving radar has discreet components—front antenna, sometimes a rear-facing one in back—plus a control/display module and remote control. Designed for permanent mounting in a vehicle, occasionally waterproof versions are installed on motorcycles.

Newer moving radar models have two features that make them particularly lethal. Same Lane mode allows the officer to clock same-direction vehicles ahead of the rolling cruiser. If the radar has a rear antenna it can clock faster vehicles as they come up from behind.

Fastest Speed mode allows the radar to sample multiple targets and display the speed of the fastest. Using this feature it’s easy to clock a motorcycle passing an eighteen-wheeler, an impossible feat for conventional radar. Learn more about this type of radar.

Stalker DSR police radar shows 36 mph speed of the oncoming minivan (nearest, on left) and the 54 mph distant SUV (headlights on), the fastest vehicle. The 51 mph speed is patrol (cruiser) speed.

With one exception, state highway patrols prefer moving radar. In Pennsylvania, the law permits only the State Police to use radar and then only in stationary mode. Hand-held radar, usually K-band Decatur models, have been the mainstay of the Pennsylvania State Police for years.

Without access to radar, many local police and sheriff’s departments in the state use time/distance computers like VASCAR. These time a vehicle between two reference points and display its average speed. The technology works fine, but it’s more labor-intensive than just pointing a radar gun toward the target.

Newer radar models have two features that make them particularly lethal. Same Lane mode allows the officer to clock same-direction vehicles ahead of or behind the rolling cruiser.

Fastest Speed mode allows the radar to sample multiple targets and display the speed of the fastest. This usually includes speeders trying to hide behind slower cars. Learn more about this type of radar.

Radar can transmit continuously or be placed on hold, ready to fire but not transmitting. With no signal present there’s nothing to detect, neutralizing a radar detector. When a target draws near, a button-press triggers the radar and a speed appears almost instantly.

Officer preference dictates the choice. Some let it run constantly, content to get fewer customers except for the brain-dead. Aggressive officers are more likely to use instant-on, hoping to outwit drivers packing radar detectors.

Photo Radar

Photo radar, also called the mobile speed van, is an automated system that combines K-band or rarely, Ka-band, radar with a camera and powerful strobe flash. Mounted in a van or SUV, it shoots a beam of radar across the road at an angle and runs continuously. It’s unusually difficult radar to detect and most detectors won’t alert until too late.

Radar Frequencies

North American radar can operate on X, K or Ka band. About one percent of the 100,000-odd radar in service nationwide use X band, 15 percent use K band and the rest operate on Ka band.

X band radar has nearly disappeared except in one holdout state, Ohio, whose highway patrol prefers X band and its wider beam. But others aren’t quite so particular and everywhere else there’s been a wholesale shift to Ka band.

How Far Away Can it Get Me?

Modern radar can clock the red car or the beer truck behind it, as well as the yellow car in front of the cruiser.

Even in a worst-case situation like our Hill/Curve test site, good detectors give half a mile of warning, plenty of time to react. Skeptics aside, the right radar detector can more than even-up the odds.

On a busy highway, a moving-mode clock usually occurs at less than 1,000 feet, often much closer. Radar merely displays a speed—it’s the officer’s responsibility to determine which vehicle the radar is looking at. Legally at least, the officer is required to establish a tracking history before taking action.

Done right, this can take several seconds, more than enough time for an alert, radar detector-equipped driver to spike the brakes. Learn more about radar range.

Places To Expect Radar

On highways without a center divider, the most common encounter is to meet an oncoming cruiser. If traffic volume is moderate-to-heavy, the officer will likely drive in the fast lane, keeping other vehicles from blocking the radar beam.

If you’re driving on a highway with a center divider, look for radar in a cruiser parked on the side of the highway. A center divider prevents the U-turn necessary for officers to work opposite-lane traffic in moving mode. Instead they’ll park and target vehicles traveling in the same direction. Freeway on-ramps are a favorite parking location.

Some dismiss detectors as mere ticket-notification devices, claiming that instant-on radar can beat it. Sometimes that’s true—get hit at point-blank range by instant-on radar and the cop usually wins.

But a quality radar detector can spot the same radar from miles away as the officer targets other vehicles.

Features to Look For

If you commute or drive anywhere near a city, a model with GPS is the best bet. Satellite technology lets it lock out nuisance signals like automatic door openers. Without GPS it’ll alert every time you pass within half a mile of a Walmart. View the best GPS-enabled detectors.

Something else to look for: Good K-band filtering. Without it, expect to be plagued by endless false alarms. A lot of these can be blamed on Blind Spot Monitoring (BSM) systems on cars. Most use radar, warning the driver when a lane change is risky.

Some police radar guns use the same K-band frequency, but their number is tiny compared to millions of BSM radar. The problem continues to worsen as BSM radar appears on an increasing number of cars.

For example, of the 93 K-band alerts we logged during one 1,300-mile road trip recently, 99 percent were caused by BSM radar. Four alerts were from roadside radar message trailers. None of them were police radar guns.

Overview of modern police radars used in Russia

28.12.2020

Police radar – a device for determining and fixing the speed of a car. Radars are actively used to control the speed limit in almost all countries of the world. There are two types of police radars: radio frequency and laser.

Radio frequency radar (Doppler radar) emits a high-frequency X-, K-, or Ka-band radio signal in the direction of a moving vehicle. The reflected signal returns back to the radar with a changed frequency. Having received the reflected signal, the radar computing module determines and displays the speed of the vehicle in the direction of which the speed was measured.

The second type of police radar is a laser radar (lidar) or, as it is often called, optical. The lidar emits short laser pulses outside the visual range in the direction of the car. These pulses bounce off the vehicle and are picked up by the radar. The difference in time between the emission and reception of the laser is converted by the radar computing module into the distance to the measurement object, and based on the successive change in distances at equal time intervals, it calculates and displays the speed of the vehicle.

Radar is often incorrectly called a device that is opposite in principle of operation – a radar detector – a passive receiver of police radar signals that warns the driver about the need to comply with the established speed limit. Police radars are installed mainly on dangerous sections of roads: a radar detector that warned the driver about the danger in time, mainly contributes to the safety of the driver, his passengers and pedestrians, rather than simply helping to avoid another fine. This article is devoted to an overview of the most popular police radar models in Russia.

Iskra-1 Radar

The Iskra-1 radar is a reliable and efficient K-band speed meter. For 15 years, the radar has been successfully used by road guard services to control the speed limit on the roads of Russia. Iskra-1 operates at double the K-band frequency, which significantly increases the reliability of measurements under adverse weather conditions. A distinctive feature of the Iskra-1 models is the monopulse method for measuring speed. This mode ensures high performance of the device: the radar calculates the parameters of the car’s movement in just 0.2 seconds. At the same time, the radar is practically invisible to all foreign-made radar detectors that are not adapted to Russian conditions: they all perceive the Iskra’s short-pulse signal as interference.

Features
Device type	radar
Operating frequency of the speed meter	24050-24250 MHz (K-band)
Controlled driving directions	all directions
Speed ​​measurement mode	stationary, patrol (on the move)
Detection range	up to 800 m
Speed ​​measuring range	30—220 km/h
Measurement error	±1 km/h

Iskra-1V is designed to operate in a stationary mode, mainly in one direction. The radar makes it possible in almost any conditions to identify a vehicle with the highest speed in the traffic flow, exceeding the speed of the flow by only 5 km/h.

Iskra-1D is the first Russian radar capable of operating in all directions in a moving patrol car. In one second, the radar manages to make a five-fold measurement of its own speed and the speed of the target, eliminate possible errors, process the measurement results and display them on a scoreboard that sequentially displays the target’s speed, own speed and time since the beginning of the measurement.

Binar Radar

A feature of “Binar” is the presence of two video cameras: the first serves for a wide overview of the traffic situation, the second shoots a close-up of the offender’s car with a distinguishable license plate at a distance of up to 200 meters. The device is able to work stationary or while a traffic police patrol car is moving. The presence of two video recordings in addition to the radar readings makes it easier to control the situation on the road and increase the reliability of identifying a traffic offender. “Binar” is equipped with a non-volatile memory card in SD format, is lightweight, can be charged from the car’s on-board network and can be synchronized with a computer. Radar control is carried out using a remote control or touch screen.

Police radars and how they work

Since law enforcement began using radars – vehicle speed control and measurement devices – the radar detectors have followed them.

In turn, the purpose of radar detectors is to catch and warn the car owner about radar signals in time. Police radars are usually located in life-threatening places: where drivers like to speed up and “drive”. This may lead to accidents. Having received radar detector signal about a speed meter ahead, the driver will slow down.

Today, the state traffic police use different radars, which differ in the principle of operation and appearance. Technologies are constantly being improved and updated, ahead of time. Manufacturers of radar detectors, in turn, do not sleep, but go one step behind.

Despite the opposite purposes, radars and radar detectors work on the same principle: they detect optical or electromagnetic waves. Radio frequency police speed meters operate in the K-, Ka-, X bands. Radars locate vehicles by generating radio or optical waves. The signal reaches the target, is reflected and returned to the radar. Next, the reflected signals are recorded. Thus, speed data (in Russia they are measured in km / h) are recorded on the device. Radars can pick up signals at the speed of light. Such radars are divided into mobile (portable, manual) and stationary (usually mounted above the carriageway of a particularly dangerous section of the road).

The so-called Doppler effect is most commonly used to accurately measure vehicle speed. To do this, the traffic police officer needs to direct the radar to the selected vehicle, install the device over the carriageway or near the road, or move with the radar turned on towards the target. When the car moves towards the radar, the frequency of the signal increases, which allows you to “catch” the intruder.

The traffic police have to resort to deceit in order to catch and punish traffic offenders. 9 are often used in their ranks.0006 impulse police radars , which measure the speed of a car using not constant, but short emissions (0.
