Abstract:

To address the problems of high power demand, low deception fidelity, single jamming mode, and insufficient real-time performance in traditional jamming methods against active radar seekers, a one-bit multi-modal jamming countermeasure method based on a multi-station networking architecture is proposed. Firstly, the method achieves high-precision parameter estimation of non-cooperative radar signals through collaborative data fusion between master and slave stations. Secondly, based on the single-frequency time-varying threshold quantization technology, it dynamically adjusts multi-dimensional parameters of quantization indicators including amplitude, frequency, phase, and signal-to-threshold ratio to flexibly generate various jamming patterns such as single-target deceptive jamming, multi-target deceptive jamming, radio frequency suppression jamming, noise suppression jamming, and multiple coordinated jamming patterns. Finally, combined with target spatial coordination and precise time delay control, it realizes the synchronous matching between jamming signals and real echoes. Simulation experiments show that under the four-station networking configuration, real targets are confused or overwhelmed by false targets in the countermeasures against the imaging function of radar seekers, resulting in a significant degradation of image clarity; in the mono-pulse tracking phase, the energy of real targets can be effectively suppressed, leading to the loss of real targets in constant false alarm rate detection and subsequent locking onto false tracks. By combining multi-modal jamming patterns with a multi-station collaborative architecture, this method not only reduces the power demand and hardware complexity of traditional jamming systems but also improves deception fidelity and real-time response capability. The feasibility and effectiveness of extending one-bit jamming technology to the field of radar seeker countermeasures is fully verified, which provides a technical path for the design of low-complexity and distributed jamming systems.

Key words: one-bit jammer, radar seeker, synthetic aperture radar (SAR) imaging, mono-pulse search and track function
