星载SAR欺骗式干扰信号的实时产生技术研究

为了在电子战系统中对敌方星载合成孔径雷达（SAR）雷达进行有效干扰，文中提出了一种新颖的星载SAR欺骗式干扰信号的实时产生技术。该技术首先通过对分布式大场景的干扰调制函数的离线及分块并行计算，降低了干扰信号产生的复杂度和计算量; 然后，通过实时卷积产生欺骗干扰信号，从而实现对敌方星载SAR系统的实时欺骗干扰的目的; 最后，试验干扰机的测试数据和仿真结果说明了方法的有效性。结果表明：该方法不但可以提供可信赖的干扰效果，而且在实践应用中具有一定的实时性。

Research on Real-time Generation Technique of Deceptive Jamming Signal for Space-borne SAR

In this paper, a novel deceptive jamming signal generation method against the space-borne synthetic aperture radar (SAR) is proposed for the electronic warfare (EW) system. By using the off-line parallel computing for jamming modulation function in the distributed sub-scenes, the proposed algorithm can highly reduce the computation burden of extended scenes for real-time deceptive jamming. The measured data from an experimental jammer system and the simulation results are used to demonstrate the performance of the proposed method. It is shown that the proposed method provides reliable jamming performance and can be implemented in real-time application.
