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.
