摘要
针对距离欺骗干扰下反导雷达跟踪弹道导弹误差增大的问题,建立距离欺骗干扰下雷达量测模型,并提出了一种基于概率数据互联滤波(PDAF)的抗距离欺骗干扰跟踪算法.该算法首先基于信号似然比预处理、角度χ^2检验以及m/n逻辑准则对落入确认波门的候选回波进行干扰综合鉴别,然后根据干扰鉴别结果采用不同的状态更新策略.仿真结果表明,该算法不仅拥有良好的干扰鉴别能力,同时可以利用假目标的角度信息改善跟踪精度.
Aiming to solve the problem that the anti-missile radar’s ballistic missile tracking error increases under the range spoofing, this paper establishes the radar measurement model under the range deception jamming,and proposes a tracking algorithm against range deception jamming based on the probabilistic data association filter(PDAF). The first step of the proposed algorithm is to carry out the comprehensive interference identification for the candidate echoes falling into the confirmation gate according to the signal likelihood ratio preprocessing,the angle χ^2 test and the m/n logic criterion, and the next is to adopt different strategies for status update based on the jamming identification results. Simulation results show that the algorithm not only has good jamming identification ability, but also can improve the tracking accuracy by using the angle information of the false target.
