摘　　要：鉴于传统算法存在的问题及成因,提出了一种基于扩展孔径的合成孔径雷达(SAR)欺骗干扰算法,论述了改进算法的原理和流程,解决了实际应用中传统SAR欺骗干扰算法在未知方位向参数的情况下,无法在方位向实现精确定位干扰和干扰图像完全聚焦的问题.仿真结果表明该方法原理正确,具有工程应用价值.A deception jamming method to SAR based on extended aperture is proposed in the view of the problem existing in general deception jamming method. The principle and steps of the improved method are presented. The method gives a solution to the problem of how to set a focused jamming image on an appointed area in the case of unknown azimuth parameters. Results of simulation indicated that the principle of the method is correct and valuable in engineering applications.
