机载火控雷达距离拖引目标的交互式多模型跟踪方法

An IMM Tracking Algorithm on RGPO Target in Airborne Fire Control Radar

针对机载火控雷达中可能出现的距离门拖引欺骗,给出了一种基于交互式多模型的目标跟踪方法。把该方法和常规的单目标跟踪方法进行了仿真比较。结果表明,该方法能充分利用欺骗回波测量,对释放距离拖引欺骗干扰的目标维持较稳定地跟踪,并能获得较高的目标跟踪精度。

An algorithm based on variable structure interacting multiple model is presented to track range gate pull off （RGPO） target in airborne fire control radar. Simulations are made to compare with conventional single target track algorithm. The results show that this algorithm can take advantage of the measurements of deception echoes to track the target more stably as well as more accurately in the presence of RGPO.
