摘要
针对线性调频连续波(LFMCW)雷达中存在的距离-速度耦合及多目标频谱配对问题,提出了一种改进波形设计的方法。该方法通过发射梯形波调制的连续波信号,不仅可以解距离-速度耦合,而且能进行上升段和下降段频谱配对。仿真结果证实了该方法的有效性。
Aiming at the problems of range-velocity coupling and multi-target spectrum matching in linear frequency modulation continuous wave（LFMCW）radar,this paper proposes a method to improve waveform design.By transmitting continuous wave signal modulated by trapezoidal wave,not only the range-velocity coupling can be solved,but also the frequency spectrums of rising segment and falling segment can be matched.Simulation results validate the validity of the method.
