Analysis of the effectiveness of the mismatched sidelobe-free compression filter in the presence of Doppler frequency shift is performed. Here the Barker-coded signal is considered as phase-shift keyed signal. Ambiguity functions of the mismatched and the matched filters were constructed. Comparative analysis of ambiguity functions of both filters was(More)

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(More)
The mismatched sidelobe-free filter is proposed for compression of phase-shift keyed signals with increased processing gain. The search of a combination of phase-shift keyed signals and mismatched sidelobe-free filter, providing the best compression effectiveness, is performed. The analysis of effectiveness of the proposed filter is carried out. The(More)
The mismatched sidelobe-free filter is proposed for phase-shift keyed signal compression in the presence of Doppler frequency shift. Analysis of effectiveness of phase-shift keyed signal compression using the proposed filter is carried out for different values of Doppler frequency.
Analysis of the impact of distortions in receiving and transmitting path of the radar on the performance characteristics of Barker code compression is carried out. The investigation of performance characteristics of Barker code compression by a mismatched filter in the presence of signal distortions is performed.
Effectiveness analysis of range ambiguity mitigation methods with usage of multiple pulse-repetition intervals is performed. The method of range ambiguity mitigation, when using different pairs of pulse-repetition intervals on even and odd scans, is proposed. Theoretical basis of the method is presented. The procedure of hypotheses formation of unambiguous(More)
