摘要
针对辐射限制下的目标跟踪问题,提出了一种机载雷达、红外传感器(infrared search and track,IRST)、电子支援措施(electronic support measure,ESM)协同跟踪与管理的方法。针对雷达、红外、ESM量测时间不一致的特点,采用顺序处理结构的多传感器集中式融合方式对目标进行跟踪,利用跟踪过程中的预测协方差与预定门限进行比较控制雷达辐射,并分析了红外、ESM不同间歇时间、不同控制门限与雷达辐射时间的相对关系。研究结论有助于提高作战飞机的抗侦察和抗干扰能力,从而提升整体的生存能力。
For target tracking problem with emission constraints,an airborne radar/infrared search and track(IRST)/electronic support measure(ESM) synergistic tracking and management method is proposed.Since the measurements of radar/IRST/ESM are not coming at the same time,sequential centralized multisensor fusion algorithm is chosen for target tracking,the comparison of the predicted covariance and the given threshold is used to decide the radar to radiate,and the relation between radar's radiation time with different IRST/ESM intermissions and different thresholds is analyzed.The research conclusion can help to increase the combat aircraft's concealment capacity and survival capacity.
