The Study Of Vehicle's Anti-Collision System Based On Millimeter-Wave Radar

With improvement of the economic level, the number of cars is increasing year by year, while the highway construction is relatively slow.This will inevitably bring the frequent traffic accidents and other traffic problems which threat people's lives and property safety. This paper designs an active anti-collision system which atrracts drivers'attention by the sound-light alarm to reduce the incidence of accident.On the basis of data collection and collation, according to braking process, an auto safety braking dynamic model is established in this paper.Meanwhile the metering distance principle of radar is introduced and the ADS model is constructed. By comparing the current range-finding sensors, the system constructs the automotive anti-collision system taking MMW radar sensors and AT89S52 as the core.Auto's anti-collision millimeter-wave radar complies with the trend of automobile intelligent and safety at home and aboard.This paper investigates the millimeter-wave impact-proof system, constructs the hardware system and draws the principle diagram. With the constant perfection and in-depth research of the system, it will bring great economic benefits and social benefits.
