A new type of detection method using the truncated statistic(TS)constant false alarm rate(CFAR) technique is proposed based on the singly right truncated Rayleigh distribution model and to solve the problem that the target detection performance of the frequency-modulated continuous-wave(FMCW)radar degrades in high-target-density situations.The first step of the method applies the two-dimensional(2D)fast Fourier transform(FFT)to transform the radar beat signal into a 2D FFT magnitude spectrum.Then a 2D windo...
