Abstract本发明涉及一种基于毫米波雷达的路口并道辅助预警系统及方法,系统包括:信号发射模块、信号接收模块、信号处理模块和信息显示模块;方法包括:中频信号分为两组频率信号;将每组频率信号分别进行FFT和OS‑CFAR过程,通过相位处理进行距离与速度估计;另一组中频信号进行FFT处理,提取与主通道FFT结果相对应的频率点数据,进行干涉比相,得到点迹的角度信息,得出点迹的方位信息;将位置与速度值相近的若干点迹信息进行凝聚处理,并对凝聚后的目标进行跟踪滤波。本发明采用毫米波雷达作为路口车辆信息检测方式,通过向感兴趣区域发射微波实现对车辆的实时信息显示及跟踪,再通过信息显示屏为驾驶员提供交通信息,已达到避免交通事故的目的。
Other AbstractThe system has a signal receiving module comprising two receive antennas and an intermediate-frequency processing module. The intermediate-frequency processing module processes two paths of a reflected signal by a signal pre-processor. A signal processing module is connected to the signal receiving module. The signal receiving module outputs an intermediate frequency signal, analog and digital sampling data. An information display module is connected to the signal processing module. The information display module receives a processing result for displaying a distance value of a target, speed and track information.
