摘要
根据SAR位置参数、运动参数、雷达波形及SAR与保护目标和干扰站的几何关系,给出SAR欺骗干扰信号形式,通过点、多点保护目标的仿真确定了工程上可行的产生欺骗干扰信号方法及步骤,并对产生了保护点目标及多点目标的干扰信号,进行了成像算法验证,证明产生的欺骗干扰信号是正确的。文中的欺骗干扰信号产生方法并不限定干扰站、保护区处于SAR的波束主瓣内,对SAR欺骗干扰信号产生的实现有较普遍意义。
Based on SAR jamming geometry model and radar waveform, the signal model of SAR deception jamming is presented, and the simulation method which is feasible in project is confirmed. The jamming signal is produced to protect point or multi-points target, and is validated through SAR imaging algorithm. The method discussed in the paper is not limited to the occasion in which the jamming station and the protective zone are situated in the main lobe, and it is of significance for generating SAR deception jamming signal.
