Research On Multiple-Phase-Sectionalized- Modulation Based Frequency Shift Jamming Method For Pulse Compression Radar

Abstract

In order to expand the jamming range of frequency shift jamming, this paper presents a multiple-phase- sectionalized-modulation (MPSM) based frequency shift jamming method for pulse compression radar. Based on the principle of frequency shift modulation, the jamming position can be controlled. Then, the jamming signal is divided into multiple sections, and modulated with different phases to expand the jamming range, so as to generate the local barrage jamming effect against the pulse compression radar. Theoretical analysis and simulation results show that this method can obtain partial process gain to reduce the need for jamming power effectively, generate local barrage jamming effect with controllable position and jamming range by reasonably choosing jamming parameters.
