| 摘 要： | 汽车防撞雷达中存在严重的多雷达电磁波交叉干扰.为了解决这一问题,提出了以随机斜率的三角波LFMCW为雷达发射波形的解决办法.利用此种波形后,干扰信号进入雷达后,相当于增加了雷达接收机的噪声,而不会产生单频频谱从而造成虚警.仿真证明,随机斜率LFMCW既不增加信号处理复杂程度,也不会导致成本上升,是电磁波交叉干扰的良好解决方案.

| Abstract: | In the automotive anti-collision radar, there are serious crossed jamming between the multiple radars. To solve this problem,this paper puts forward the triangle LFMCW with random slope as the transmit wave of automotive anti- collision radar. After this waveform is adopted, when the jamming signal into the radar, it will be regard as noise but targets. The simulation results prove that this waveform is not to increase the signal processing complexity, and also will not lead to rising costs. So the triangle LFMCW with random slope is a rational solution of crossed jamming. |
