基于FMCW雷达测距的车辆防碰撞系统
A vehicle anti-collision system based on FMCW radar ranging
摘要
Abstract
Aiming at the frequent traffic accidents,the driver encounters a potential collision is not timely,a vehicle anti-colli-sion system is designed based on radar ranging.The system uses 24 GHz radar sensor for the front-end signal transceiver module,floating-point DSP chip as the core sampling and processing of data.Radar uses a continuous triangle wave frequen-cy modulation and applies Chirp-Z algorithm for spectrum refinement of radar beat frequency signal to improve the range ac-curacy.Simulation results show that the system can effectively get the distance and the relative speed of the vehicle in front, and achieve security warning.关键词
