摘要：

针对干扰主动雷达导引头时传统手段存在的功率需求高、欺骗逼真度低、干扰样式单一及实时性不足等问题，提出一种基于多站组网架构的单比特多模态干扰对抗方法。首先通过主从站协同数据融合，实现非合作雷达信号的高精度参数估计。其次基于单频时变阈值量化技术，动态调节量化指标的幅度、频率、相位及信号阈值比等多维度参数，灵活生成单目标欺骗、多目标欺骗、射频压制、噪声压制及多种协同干扰样式。最后结合目标空间协同与精确时延控制，实现干扰信号与真实回波的同步匹配。仿真实验表明，四站组网配置下，在成像功能对抗中真实目标被假目标混淆或淹没，图像清晰度显著下降；在单脉冲跟踪阶段可有效压制真实目标能量，导致恒虚警检测丢失真实目标后锁定虚假航迹。所提方法通过多模态干扰样式与多站协同架构的结合，既能降低传统干扰的功率需求与硬件复杂度，又能提升欺骗逼真度与实时响应能力，充分验证了单比特干扰技术拓展至雷达导引头对抗领域的可行性与有效性，为低复杂度、分布式干扰系统设计提供技术路径。

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
