The mismatched sidelobe-free filter for compression of phase-shift keyed signals with increased processing gain

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 proposed filter is supposed to be used in signal processing software of the perspective radar.
