摘要
近年来针对驾驶安全性的迫切需要,汽车防撞雷达系统得到了深入研究和广泛应用.文中针对采用毫米波雷达技术的汽车防撞雷达系统,提出了利用小波分析技术对雷达中频信号进行处理的方法.小波技术的应用可以方便地对雷达中频信号按照频率的不同进行分解,有助于多目标环境下的识别,能有效地将由于道路、路边栅栏、树木和楼宇的影响而导致的干扰虚警信号滤除.
In recent years,automobile anti-collision radar system is being studied and used widely to satisfy the need of the safety of driving.The signal processing technique of wavelet is put forward to serve the automobile anti-collision radar system with millimeter-wave radar technology in this paper.The application of wavelet technique can offer convenience to decompose signals according to frequency.It also can help distinguish multi-targets and remove validly the disturb and virtual warning of signal which is caused by road,fence,trees and buildings.
