Abstract

The invention provides a high-precision microwave radar ranging system which can be used for detecting multiple targets in a close range and a long range and at different angles, different ranging calculations can be carried out according to different distance models, reliability is improved through a radar dead angle auxiliary detection unit, and safety accidents can be reduced to the largest extent.

Description

technical field [0001] The invention relates to the field of microwave communication, in particular to a high-precision microwave radar ranging system. Background technique [0002] Traffic accidents have become "the world's number one hazard". How to ensure driving safety and how to reduce the incidence of related traffic accidents has become a topic of concern to the whole society. In this background, the research and development of automobile early warning technology has become a hot spot, among which the research and development of automobile collision avoidance system has very important practical significance and application value. [0003] Automobile anti-collision radar can be realized by ultrasonic, laser, infrared and microwave technologies, but the first three are easily affected by bad weather and environmental factors, and the detection accuracy cannot be guaranteed. Therefore, domestic and foreign experts focus on microwave radar. [0004] In intelligent transp...
