摘要
针对惯性导航系统(Inertial Navigation System,INS)/被动微波/合成孔径雷达(Synthetic Aperture Radar,SAR)多模导引头,分析了弹载条件下,有源欺骗干扰和场景散射干扰影响的特点,提出了利用被动导引头辐射源参数测量能力的有源欺骗干扰抑制方法,以及利用任务规划所装订的目标位置和惯导误差模型的场景散射干扰抑制方法,给出了详细的干扰抑制流程。典型场景的仿真表明了所提干扰抑制方法的有效性,结合仿真结果分析了干扰抑制处理带来的问题,提出了解决思路。
Under the missile-borne SAR operation in INS/passive-radar/SAR seekers, the characteristic of the influence of active deceive jamming and the scatter-wave jamming is analyzed. The passive-radar＇ s ability to measure the emitter＇ s parameters is to be used to penalize the active deceive jamming, while the target position and INS error model set during task programming is to be em- ployed to suppress scatter-wave jamming. The jamming suppression flowchart is also given. Then the simulation results in the typical jamming scenario prove the validity of the proposed method. In the end, problems emerging with jamming suppression and the corre- sponding solving ideals are discussed.
