Summary:Among the various types of jamming, active deception jamming has similar characteristics to the transmitted signal. The jamming seriously affects the detection and tracking of real targets by radar. In recent years, waveform design has become an effective anti-jamming method with the maturity of waveform generator technology. However, most anti-jamming waveforms are only designed to combat a single kind of jamming. To compensate for the shortage of existing waveforms that cannot simultaneously combat compound deception jamming, we construct an interpulse-intrapulse joint frequency coded(I-IJFC) anti-jamming waveform and analyze the anti-jamming process flow. Moreover, to reduce the influence of residual jamming, we propose an intrapulse frequency-coded method based on jamming parameters estimation. The waveform can be used against cross-pulse repeater deception jamming(CRDJ) and interrupted sampling jamming(ISJ). Then, to solve the problem that the existing algorithm cannot realize the coherent accumulation of the proposed waveform, we propose a coherent accumulation algorithm of subpulse rearrangement compensation and nonuniform discrete Fourier transform (SRCNDFT). The simulation examples show that the waveform proposed in this paper performs better against compound deception jamming than existing waveforms, and the proposed algorithm can realize the coherent accumulation of I-IJFC echo signals.
