摘要
为解决多目标环境下对称三角LFMCW雷达上/下扫频段目标配对困难的问题,提出了一种利用运动目标在上/下扫频段频谱的对称性,并结合各个目标模糊多普勒速度的差异,实现上/下扫频段目标的准确配对及距离速度去耦合。仿真结果证明了该方法的有效性。
To solve the problem of targets pairing between positive and negative frequency sweep in triangular LFMCW radar for multi targets, a method of velocity pairing is proposed. The method realizes targets pairing and range-velocity decoupiing by the symmetry of the spectrum between positive and negative frequency sweep and the difference of the ambiguous Doppler velocity. The effectiveness of the method is demonstrated by simulations.
