According to a study by the World Health Organization, one million two hundred thousand people die every year around the world! Another 20-50 million are injured. Russia in such "competitions" is torn in the lead in all categories. Another thing is also known: the number of accidents and the severity of their consequences increase with increasing speed. It is estimated that when the average speed decreases by 1 km / h, the number of accidents decreases by 4%. Alas, today we most often observe the high-speed mode not for safety reasons, but for fear of meeting with the radar. And imagine the absurd situation: on all roads, every kilometer there is a policeman with a radar - you simply won’t be able to drive … But at the same time, out of the hundred people who, according to statistics, do not return home today, many would have survived!

In short, I propose not to get mad at the radars, but to look at them through the eyes of the developer. If only because it, in my opinion, is simply interesting.

The first speed gauges for traffic police were created in the United States shortly after World War II. They used a carrier frequency of about 10.5 gigahertz (X-band), which defined this range as standard for many years. In some places we still encounter Soviet development - various modifications of the Barrier series radars. With increasing speeds and flux density, I had to “teach” radars to see the fastest target against the background of traffic flow. Moreover, on congested roads with two-way traffic, it was required to determine the direction of movement of targets. In 1997, the first modification of the Iskra-1 meter from Simikon was certified, and almost simultaneously the Falcon of Olbia, also from St. Petersburg, appeared.

Various modifications of these devices make up the main fleet of speed meters in Russia today. The main difference between the two: in Sokol, the traditional X-band frequency is used, and for Iskra, another standard is selected and certified - 24 gigahertz (K-band). The higher frequency made it possible to almost halve the dimensions and weight of the device compared to the Falcon, not to mention the outdated Barrier. Then the next modifications of the Iskra learned to work in a moving patrol car. They can fix oncoming and passing targets, acting both forward in the direction of travel and in the opposite direction. Another is the ability to determine the speed of passing cars with a minimum difference with the speed of the patrol.

How accurate are the radar readings? I will say right away that the guaranteed measurement range is 300-400 m, and the real one is 800 m. However, do not “load” traffic cops with questions on this topic. The fact is that before recording the result, the radar repeatedly measures the speed of the target, comparing the obtained values. In cases where, under the influence of interference or other factors, the accuracy of the measurements cannot be guaranteed, the result will not be displayed at all. In other words, the radar shows either the correct situation or does not show anything!

Simultaneously with the measurement of speed, the radar timer starts. You can also make sure that you are presented with the speed of a target that was moving in the same direction as your car. There is a triangular luminous arrow on the side surface of the Iskra-1 handle. By the way, ten minutes are given to erase the memory after measuring the speed - this is the time allotted for compiling the protocol.

New radar models have recently been launched into production: at Simikon, this is Radis. In addition to all the capabilities of Iskra, it is capable of transmitting data via a USB port or over the air and has many service capabilities. And to replace the "Falcon" came "Golden Eagle". During its development, the company "Olbia" also mastered the K-frequency range.

Life forces the creators of radars to pay special attention to the evidence base. Video frames "Frame-1", produced by "Simicon" for about three years, allow you to capture a sequence of photos of the traffic situation, where each has data on the measured speed. In addition, Sokol-Visa and Avtoskan devices are also produced in Russia. There is also a Nissan Patrol GR / Patrol complex - it is permanently installed in a car.

The future in speed control belongs to fully automated systems - they are also called photoradars. They are able to reliably determine the intruder without the participation of the operator, even by one fixed photo frame. The main technical problem in this case is to ensure that the speed of the particular car shown in the photo is measured. The KRIS-1 complex is capable of this, which is already being used both in Moscow and in the Leningrad region. Its peculiarity is the presence of a special radar with a very narrow, needle-shaped radiation pattern. The camera captures a continuous image - for preservation, only frames with a license plate in the visibility range are selected. The computer simultaneously analyzes all the received signals, accurately comparing speed and image measurements.

Automated systems are good because they deprive the driver of the opportunity to argue with inspectors, nodding either at the radar or at the speedometer. Or maybe a bad dream will come true and terminators with radars will appear on every kilometer? So far we have not thought of it yet …
