Electronic Warfare (EW) is a type of warfare that influences radio emissions (radio interference) on the radio electronic means of control, communication and reconnaissance systems of the enemy in order to change the quality of military information circulating in them, protect their systems from similar effects. (properties of the medium) of the propagation of radio waves.

Radio frequency radar (Doppler radar) emits a high frequency radio signal of X-, K- or Ka-band in the direction of the car. The frequency of the reflected signal varies in proportion to the speed of movement of the object. Having received the reflected signal, the radar measures the frequency deviation and calculates the speed of the car. The resulting speed value is displayed on the radar display or transmitted to the situational center, in case the radar is stationary.
The second type of police radar is laser radar (lidar) or, as it is not rarely called, optical. Lidar emits short laser pulses outside the visual range (IR), with a fixed time interval, in the direction of the car. These pulses are reflected from the vehicle and are received by a laser meter. Lidar captures the change in the distance to the object by the delay time of each reflected pulse. A digital lidar device calculates the speed of a vehicle using range data for a fixed amount of time.
The Iskra-1 radar is a reliable and efficient speed meter operating in the K-band. For 15 years, the radar has been successfully used by road monitoring services to control the speed limit on the roads of Russia. Iskra-1 operates at double the frequency of the K-band, which significantly increases the reliability of measurements under adverse weather conditions. A distinctive feature of the Iskra-1 models is a single-pulse method for measuring speed. This mode provides a high speed device: the parameters of the movement of the car radar counts in just 0.2 seconds. At the same time, the radar is almost invisible to all non-adapted for Russian conditions radar detectors of foreign production: they all perceive the Iskra short-pulse signal as a hindrance.
Mobile radar "Sokol-M" is an autonomous radar velocity meter operating in the outdated X-band. The device is designed to determine the speed of oncoming cars only. Overall, easy to use, the radar is able to control the speed of both individual cars and moving in the stream at a distance of 300-500 m. It is perfectly recognized by “white” radar detectors of any price category. The Sokol-M radar was discontinued in 2008, but due to its high reliability, ease of handling and relatively small price, it is widely used now in Russia and the Commonwealth countries.
A special feature of the Binar is the presence of two video cameras: the first is for a broad overview of the traffic situation, the second is shooting close-ups of the intruder’s car with a distinguishable number plate at a distance of up to 200 meters. The device is able to work stationary or while driving a DPS patrol car. The presence of two video recordings in addition to the radar readings simplifies the monitoring of the situation on the road and increases the accuracy of identifying the traffic violator. "Binar" is equipped with a non-volatile memory card in SD format, has a low weight, is able to charge from the on-board network of the car and can be synchronized with the computer. The radar is controlled using a remote control or touch screen.
Radar "Radis" has high accuracy and fast measurement speed with the ability to select the nearest or fastest car from the traffic flow. The device is capable of measuring the speed in the opposite and in the same direction, it is equipped with two displays with bright backlighting and has a simple control using the on-screen menu. The radar is capable of measuring the speed, charging from the on-board network of the car. The weight of the device is only 450 g. "Radis" can be installed in the cabin, as well as on the hood or roof of a patrol car using a magnetic stand. Using the remote control, the radar can be controlled remotely.
Police radar "Berkut" is designed to control the speed of single vehicles or cars in heavy traffic. Has the ability to choose the nearest or fastest car. The radar is equipped with a backlight indicator and buttons, allowing the traffic police inspector to fix the speed of the car in the dark. "Berkut" can work 10 hours without recharging and measure the speed both permanently and in patrol mode. The radar is easy to use and easily mounted on the dashboard of the car. Depending on the situation, a handle, a bracket or a video clip can be attached to the device.
During the speed determination, the Vizir radar carries out a photo and video recording of the intruder’s car, which helps the traffic police inspector in resolving disputable situations. Results of speed measurements, as well as the control date and time are entered into the snapshot taken by Vizir. The device measures in all directions and is able to work both permanently and in the patrol car. The radar is equipped with a built-in LCD display and a simple menu with a convenient location of control keys. The device has the function of automatic speed measurement and recording traffic violations. "Vizir" can be connected to an external monitor and transfer data to a computer.
The radar complex "Strelka" accurately measures the speed of all vehicles that fall within its coverage area (500 m from the installation site), regardless of the density of the traffic flow. The "Strelki" camera records the excess of the established speed limit at a distance of 350 to 50 m to the installation site and photographs the vehicle of the intruder with clearly distinguishable license plates. The received data is processed by a computer and transmitted to the information processing center via a fiber-optic line or via a radio channel.
The hardware and software complex "Arena" is designed to automatically control the speed limit on a certain section of the road. Preparation of the complex to work takes about 10 minutes. The Arena is mounted on a tripod 3-5 m from the edge of the roadway. Cars that have exceeded the speed threshold are automatically photographed, and data on violations are transmitted to the traffic police post or stored in the device memory. The radar complex is powered by a battery located nearby in a special box.
The photo-radar complex “Chris” is designed for automatic recording of traffic violations, recognition of vehicle numbers, checking them against federal or regional bases and transferring data to a remote traffic police post. The device is equipped with an infrared camera, which allows it to work at night. "Chris" is installed on a tripod near the edge of the roadway and will measure the speed of only those cars that are in the frame.
Radar "Rapira-1" is used only for stationary measurement of the speed of vehicles, able to work separately or as part of various hardware and software systems. The radar is installed at a distance of 4-9 meters above the road at an angle of 25 ° and allows you to determine the speed of the car in a narrow zone of control.
Laser radar "Lisd-2" is designed to measure the speed of movement and the distance to various objects, uses a narrow beam of light that allows you to select a specific car in a dense stream of vehicles. Lidar is made in the form of binoculars with an optical sight, it works only stationary, but measures the speed in all directions. There is a fastening of the shoulder strap and the ability to install the device on a tripod.
Laser Radar "Amata" is able to accurately measure the speed and distance of vehicles and record traffic violations using photo or video. The device works on the basis of a laser speed meter, which allows you to reliably select the car you need from a dense traffic flow. Lidar "Amata" is equipped with a target mark, which on the device display or in the photo coincides with the direction of the laser beam and is proof of the speed measurement of a particular car.
