摘要
针对线性调频连续波雷达的信号生成原理与信号处理流程,提出了一种基于相参频率快速调制的调频连续波(LFMCW)雷达干扰方法。该方法能够有效地控制需要干扰的距离与速度范围,使得LFM雷达无法正确检测地面运动目标,达到干扰雷达目标检测的目的。该干扰方法与传统的压制干扰相比具有功率小的优势,又可以达到对目标检测的有效干扰。利用实测雷达的数据处理结果验证了该方法的有效性。
With the analysis of the linear frequency modulate continuous wave (LFMCW) ground reconnaissance radar signal processing, a LFMCW radar jamming method based on coherent fast frequency modulation is proposed. The jamming range gate and velocity range arbitrarily could be set, so that the moving target could not be detected with LFMCW radar correctly. The jam- ming has the advantages with lower power cost, compared with the noise jamming method. The validity of the method is shown with the simulation results based on the real data.
