摘要

摘要: 该文利用距离向DBF技术，提出使用DBF-SAR系统抗欺骗干扰的方法。DBF-SAR系统抗欺骗干扰主要思想是，根据欺骗干扰回波方向和真实目标回波方向不同的原理，利用距离向多孔径，增大系统自由度，对各孔径接收回波使用距离向DBF技术，通过谱估计，估计出欺骗干扰方向，然后计算加权系数形成等效距离向天线方向图，在干扰方向形成零陷，实现空域滤波，抑制干扰方向信号，从而达到抗欺骗干扰的目的。仿真结果表明，距离向DBF-SAR系统能有效地抗欺骗性干扰，提高成像质量。

Abstract: Based on range Digital BeamForming (DBF) on receive in DBF-SAR system, a novel method is proposed to counter deceptive jamming. The method makes full use of the difference between the direction of deceptive jamming return and the direction of ground target return. Since DBF-SAR with range multiple apertures can improve the system freedoms, the direction of deceptive jamming are estimated through spectrum estimation algorithm. Then according to the estimated direction, the weighted coefficient is calculated to form the equivalent range antenna pattern. Since range antenna pattern has the nulls in the directions of interferences, deceptive jamming is suppressed through space filter. Simulation results show that range DBF-SAR system can counter deceptive jamming effectively and enhance imaging quality.
