摘　　要：对合成孔径雷达(SAR)实施欺骗干扰,干扰方通常需要预先侦察出SAR载机平台速度、方位向慢时间、斜视角、SAR载机平台到干扰机的最近斜距以及干扰机自身位置等关键参数,而获取这些参数通常需要复杂的侦察设备。针对这一问题,一些学者提出了一种基于多接收机协同的SAR欺骗干扰方法,该方法有效地解决了需复杂设备侦察上述关键参数的难题,简化了干扰系统的配置。为进一步提高该方法的干扰效果和实时性,提出了一种改进的基于多接收机协同SAR欺骗干扰方法。研究表明,随着生成的虚假目标离干扰机距离增大,所提方法比原有方法生成的虚假目标峰值位置和聚焦效果要好,且实时性更强。When the deception jamming is implemented on synthetic aperture radar(SAR),the jammer usu⁃ally needs to obtain some key parameters in advance,such as the speed of carrier platform of SAR,the slow time,squint angle,the nearest oblique distance from the jammer to the carrier platform of SAR,and self-position of the jammer,and so on.However,the acquisition of these key parameters usually needs complex reconnais⁃sance equipment.In response to this problem,a SAR deception jamming method based on multi-receiver coopera⁃tion was proposed by some scholars which effectively solves the problem of requiring complex equipment to recon⁃noitre the above key parameters,and greatly simplifies the configuration of the interference system.In order to further improve the jamming effect and real-time performance,an improved SAR deception jamming method based on multi-receiver cooperation is proposed.The research shows that,with the increase of the distance be⁃tween the generated false target and the jammer,the peak position of false target and focusing effect and real-time performance in the proposed method are better than that in the original method.
