Automotive anti-collision radar detection method with anti-interference and multi-target recognizing performance

Abstract

The invention discloses an automotive anti-collision radar detection method with anti-interference and multi-target recognizing performance, which comprises the following steps: step A, the range of signal strength is set through a radar signal strength setter; step B, a radar detection processor controls a radar transmitter to transmit a radar signal, and receives the radar signal through a radar receiver, after the radar signal received by the radar receiver passes through a radar signal processor, the radar signal is compared with the set signal strength of the radar signal strength setter through a radar signal comparator and is transmitted to the radar control processor so as to be processed; step C, the radar control processor carries out processing to the signal that passes through the radar signal comparator, when abnormal radar signal strength inconsistent with adjusted radar signal strength appears, the radar control processor drives an abnormal signal strength shielding transmitter to transmit a shielding signal, so as to realize radar anti-interference. The automotive anti-collision radar detection method with the anti-interference and multi-target recognizing performance has a simple structure, is good in using stability, realizes multi-target recognition and improves the anti-interference performance accordingly, thereby having high using safety performance.

Description

technical field [0001] The invention belongs to the technical field of radar communication and the field of automobile electronics, and in particular relates to an automobile anti-collision radar detection method for anti-jamming and multi-target identification. Background technique [0002] Automobile anti-collision radar detects the distance, speed and azimuth between a single or multiple targets within a certain distance in front of the car and the car, and can send out an alarm signal in dangerous situations according to the early warning system to prompt the driver to take measures. With the rapid development of technology and the gradual emphasis on automobile safety, the automobile active defense system based on automobile anti-collision radar has become an important subject of research and development. Since most of the existing automobile active defense control systems are single-vehicle systems, their It can realize the defensive control of a single vehicle. Howeve...

[0002] Automobile anti-collision radar detects the distance, speed and azimuth between a single or multiple targets within a certain distance in front of the car and the car, and can send out an alarm signal in dangerous situations according to the early warning system to prompt the driver to take measures. With the rapid development of technology and the gradual emphasis on automobile safety, the automobile active defense system based on automobile anti-collision radar has become an important subject of research and development. Since most of the existing automobile active defense control systems are single-vehicle systems, their It can realize the defensive control of a single vehicle. However, when multiple vehicles are equipped with anti-collision radar at the same time, it is easy to cause misleading, and to a certain extent, it will limit the stability and safety of the car anti-collision radar. The applicability and practicability are difficult to meet the market. needs
