Two receiver structures of phase modulated FMCW signals with low ADC sampling requirement are investigated, namely the matched filter of the dechirped signal and the group delay filter approach. The sensing performance of the investigated receiver strategies are analyzed in application to BPSK modulated chirp. Numerical simulations demonstrate that both techniques provide comparable performance for low to moderate bandwidth of the modulation signal. Matched filter outperforms the group delay receiver for the modulation waveform with large bandwidth, hence with the price of larger computational complexity.
