文摘A deceptive pull-off jamming method to terminal guidance radar is put forward in this paper.The design rules about the important jamming parameters are discussed in detail,including the number of the decoy targets in range dimension,the velocity of the range gate pull-off,and the number of the decoy targets in velocity dimension and the velocity of the Doppler frequency pull-off.Also,the steps to design these parameters are brought out.The rules and design procedure discussed in this paper have important meaning for the choice of the reasonable jamming parameters in the practical applications,which can help to obtain good jamming effect.
文摘针对距离波门拖引(Range Gate Pull Off,RGPO)干扰下机动目标跟踪性能恶化的问题,提出一种基于雷达点迹处理的机动目标跟踪算法。该算法首先使用RGPO干扰鉴别技术将跟踪波门内的雷达点迹数据分为正常点迹集与RGPO干扰点迹集,针对不同的点迹集采取了不同的状态更新策略,最后融合两类状态信息后输出目标位置。仿真结果表明,该算法的跟踪精度明显优于传统的交互多模型-概率数据关联(Interacting Multiple Model Probabilistic Data Association,IMM-PDA)算法及现有抗RGPO干扰机动目标跟踪算法。
