The high-fidelity deceptive jamming contaminated synthetic aperture radar (SAR) images are very confusing when they are interpreted for target recognition. In this letter, a novel azimuth phase coding (APC)-based method is proposed for deceptive jamming suppression, especially with characteristics of high fidelity and intermittent sampling. The deceptive jamming model is detailedly formulated, and the difference and relation related to the real target are also discussed. Then, the APC-based suppression method is proposed, where the original APC principle and how it is to be introduced into deceptive jamming suppression are deduced and analyzed. Considering the delay feature of deceptive jamming retransmission, azimuth phase modulation, azimuth phase demodulation, and azimuth filtering are successively implemented. Then, parameters discussion is carried out for a deeper understanding. Simulation results demonstrate the superiority of the proposed method.

使用方位角相位编码的高保真SAR间歇采样欺骗性干扰抑制

当将高保真度欺骗性干扰污染的合成孔径雷达（SAR）图像解释为目标识别时，它们非常令人困惑。在这封信中，提出了一种新颖的基于方位相位编码（APC）的方法来欺骗性地抑制干扰，特别是具有高保真度和间歇采样的特征。详细阐述了欺骗性干扰模型，并讨论了与真实目标有关的区别和关系。然后，提出了一种基于APC的抑制方法，推导并分析了原始的APC原理以及如何将其引入到欺骗性干扰抑制中。考虑到欺骗性干扰重传的延迟特性，相继实现了方位角相位调制，方位角相位解调和方位角滤波。然后，进行参数讨论以加深理解。仿真结果证明了该方法的优越性。
