| 摘 要： | 采用发射双周期锯齿波并结合MTD处理的方式,实现了LFMCW雷达距离与速度的解耦合。其中,针对多目标场景下的目标配对问题,提出了耦合距离目标配对法。并通过对配对后的目标进行速度解模糊,进而解算出其真实运动参数。仿真结果证明了整个处理流程及配对算法的有效性。

| Abstract: | Dual period sawtooth and moving target detection (MTD) techniques are combined in order to realize the range-velocity coupling of LFMCW radar.As for the problem of multi-target pairing,a new method called coupled range pairing is proposed.After eliminating the velocity ambiguity of pairing targets,the motion parameters can be acquired.The simulation results indicate the effectiveness of the signal process and pairing algorithm. |
