【摘要】：欺骗干扰是一种常用的干扰手段,相对于常规理想直线航迹的合成孔径雷达(synthetic aperture radar,SAR)而言,圆周SAR的航迹参数难以获取,用常规解析表达求解并进行干扰调制的欺骗干扰方法行不通,鉴于此,本文提出了一种基于多接收机的圆周SAR欺骗干扰方法。该方法不需要侦察圆周SAR的具体参数信息,直接从多接收机的斜距差中求解敌方SAR系统的参数整体,进而进行干扰调制。相比于直接测量各项SAR参数,该算法具有更高的测量精度和较强的算法稳定性,在载机存在运动误差的情况下,系统仍然可给出满意的干扰效果。本文同时分析了SAR系统精度对欺骗干扰质量的影响。最后,仿真实验验证了所提方法的有效性和可行性。
[Abstract]:Deception jamming is a common jamming method. Compared with (synthetic aperture radar,SAR (synthetic Aperture Radar) with conventional ideal straight track, it is difficult to obtain the track parameters of circumferential SAR. The deceptive jamming method based on conventional analytic expression and interference modulation is not feasible. In view of this, a circular SAR spoofing jamming method based on multi-receiver is proposed in this paper. This method does not need to reconnoitre the specific parameter information of the circumferential SAR, and directly solves the whole parameter of the enemy SAR system from the skew distance difference of the multi-receiver, and then carries on the interference modulation. Compared with the direct measurement of various SAR parameters, the proposed algorithm has higher measurement precision and better stability of the algorithm. The system can still give satisfactory interference effect when there are motion errors in the carrier. At the same time, the influence of the precision of SAR system on the quality of deception jamming is analyzed. Finally, the simulation results show the effectiveness and feasibility of the proposed method.
