对宽带雷达一维像的可控多假目标干扰

摘要

Multi-false targets jamming signal model of wideband imaging radar is studied, and controllable multi-false targets generation algorithm via amplitude and phase modulation within pulse is proposed. Based on distance, amplitude and phase of controllable multi-false targets, amplitude and phase modulation function is built, and controllable multi-false targets and multi-false targets range profile can be generated via repeating the intercepted signal modulated by this function. Numerical signal simulation results verify the model, and indicate that this method is superior to common multifalse targets of sine amplitude and phase modulation.%研究了宽带成像雷达多假目标干扰信号模型,提出了脉内幅相调制转发式可控多假目标的生成算法。该方法根据要产生的多假目标位置分布和幅相数据生成幅相调制函数,通过对所截获的脉冲进行幅相调制和转发,产生可控脉内多假目标和多假目标一维像干扰效果。数字仿真验证了该算法,表明所提出的干扰方法比常规正弦幅相调制多假目标干扰更优越。
