Phase-shift keyed signal compression using a mismatched sidelobe-free filter in the presence of Doppler frequency shift

Analysis of the influence of the Doppler frequency shift on the effectiveness of Barker code compression is carried out. The mismatched sidelobe-free filter was considered as a signal compression filter. An ambiguity function of the mismatched filter was constructed, comparative analysis of ambiguity functions of the mismatched filter and a conventional matched filter was performed.
