Radar data collection equipment uses electromagnetic wave technology. Radar is an electronic device that uses electromagnetic waves to detect targets. The radar emits electromagnetic waves to illuminate the target and receives its echo, thereby obtaining information such as the distance from the target to the electromagnetic wave emission point, distance change rate, radial speed, orientation, altitude, etc. The specific uses and structures of various radars are different, but the basic form is the same, including: transmitter, transmitting antenna, receiver, receiving antenna, processing part and display. There are also auxiliary equipment such as power supply equipment, data acquisition equipment, and anti-interference equipment.
