摘　　要：现代新型反舰导弹末制导雷达部分采用相位编码相参雷达工作体制。相位编码体制末制导雷达对压制式有源干扰和常规的欺骗式干扰有着较强的抗干扰能力。该发明针对相位编码体制末制导雷达相参积累期间,载频、脉冲重复周期不变,脉间信号调制样式变化的特性,以及相位编码信号对多普勒敏感的特性等技术特点,设计出一种间歇采样储频+多普勒调制转发的有源干扰样式。该有源欺骗干扰样式可对相位编码体制末制导雷达的时域和频域回波同时造成影响,导致雷达恒虚警检测和目标特性识别非常困难,具有良好的干扰效能。Part of modern new anti-ship missile guidance radar adopts phase-coded coherent radar working system.Phase-coded system's terminal guidance radar has a strong ability to suppress destined jamming and conventional deceptive jam⁃ming.This article introduces the characteristics of the change of the pulse interval signal and the Doppler-sensitive phase-encoded signal when the carrier frequency and the pulse repetition interval are unchanged during the phase-coordinated radar coherent accu⁃mulation.In view of this,an active jamming pattern of intermittent sampling frequency storage+Doppler modulation and forwarding is designed.This active jamming pattern can jam time-domain and frequency-domain echoes of a phase-coded terminal guidance ra⁃dar,causing radar constant false alarm detection and target characteristic recognition to be very difficult.This method has good inter⁃ference performance.
