红外/雷达交叉定位的双门限间歇式目标跟踪方法

针对组网火控雷达交替间歇跟踪中的盲期问题,提出基于交叉定位的红外/雷达双门限间歇跟踪方法。该方法首先采用改进的天线波束控制算法消除相关误差的影响;其次,通过双跟踪精度门限控制传感器工作时间,同时利用多红外交叉定位跟踪,进一步增加静默跟踪雷达的反应时间;最后,利用基于数据压缩的序贯式融合算法对异类间歇数据进行融合处理,实现了组网系统对目标的连续跟踪。仿真结果表明,该方法可以进一步减小跟踪盲期的影响,有效地提高系统的整体性能。

Method of Dual Threshold Intermittent Target TrackingBased on Infrared / Radar Cross Location

In order to solve the target-losing period problem in netted fire-control radars’ intermittent tracking,dual threshold infrared /radar intermittent target tracking method is proposed.Firsdy,improved algorithm of antenna beam control is used to eliminate the effect of correlative errors.Then,the method uses dual threshold to control sensor’s working time,and increases silent radar’ s response time by cross location of infrared sensors.At last,sequential filtering fusion algorithm based on data compression is used for dissimilar data fusion,and continuous target track is formed.Simulation results showed that this method could weaken the effect of target-losing period problem and improve system performance.
