| 摘 要： | 针对线性调频连续波雷达双差拍-傅里叶处理中的多目标配对问题,提出了一种新的多目标距离-速度联合配对法。文中分析了连续波与线性调频连续的雷达回波频谱,描述了雷达系统工作原理;然后,利用单载频回波信号测量多目标的不模糊速度,同时利用锯齿调频波测量多目标的不模糊距离与模糊速度;最后,结合距离-速度配对的方法,实现多目标的配对。仿真结果验证了方法的有效性。

| Abstract: | To solve multi-targets pairing problem in double beat-FFT processing for linear frequency-modulated continuous wave(LFMCW) radar,a new joint range-velocity pairing method for multi-targets is presented.Radar echo spectrum of continuous wave(CW) and LFMCW is analyzed,the principle of radar system is described in this paper.And then,unambiguous velocity of multi-targets can be measured by CW and unambiguous distance and ambiguous velocity of multi-targets are measured by LFMCW.Finally,combined with the method... |
