The interrupted-sampling repeater jamming (ISRJ) is a form of coherent jamming that encompasses both suppression and deception effects, with the aim of disrupting radar detection capabilities. This study focuses on anti-ISRJ techniques in the waveform domain, with a primary emphasis on waveform design combined with antijamming signal processing methods. By examining the relationship between waveform-domain adaptive matched filtering (WD-AMF) and the transmitted waveform, we demonstrate that ISRJ can be effectively suppressed when the transmitted waveform exhibits waveform-domain complementarity. We introduce a phase-coded waveform set with waveform-domain complementarity, referred to as waveform-domain complementary signal sets (WDCSS), and propose a method for generating such waveform sets with binary phase-shift keying modulation of arbitrary code lengths. The performance of WD-AMF is further enhanced by the designed waveforms, achieving complete suppression of ISRJ in any mode without reducing the radar's normal detection capability. Simulations confirm that WDCSS in WD-AMF has superior adaptive antijamming capabilities compared to other traditional waveforms, while also demonstrating its robustness under varied environmental conditions and electronic counter-countermeasures. Remarkably, this improved performance is achieved without the need for prior information of ISRJ working parameters at either the transmitter or receiver stages.
