FIELD: radar systems.
SUBSTANCE: short-range radar continuous radiation used in automated control systems of vehicles, including unmanned vehicles, in locomotive safety and control devices, in particular in devices for recording movement parameters and controlling the speed of a train, as well as in speed control devices of other ground vehicles. Improving the accuracy of measurements is achieved by forming a flat radiation phase front in the near field of the antenna over its entire cross section. At the same time, the increase in the reliability of measurements is ensured by the use of an extended antenna in the direction of the vehicle.
EFFECT: increasing the accuracy and reliability of measuring the speed of ground vehicles relative to the roadway by improving the quality of Doppler signals by improving the antenna system.
