Triangular frequency modulation continuous wave,combined with frequency domain matching,is adopted to solve the problem of range-velocity decoupling in LFMCW radars.But the algorithm based on traditional FFT can cause range precision and velocity precision decreased,because of the inherent frequency space of FFT.FFT-CZT two-stage processing is adopted to improve the range precision and velocity precision of LFMCW radar moving target.The method is proved in different bandwidth LFMCW radar and can be applied widely.
