摘要
设计了一种应用于靶场高精度测量雷达的数字式自动距离跟踪器,采用典型的二阶α-β滤波器;相比常规的距离跟踪系统,其具有多目标跟踪能力;对于远程单目标,具有自动距离解模糊和避盲区处理功能;跟踪波门产生器设计有延时插值器,可较大地提高距离跟踪精度;设计有辅助跟踪回路,主闭合回路丢失目标,辅助进行外推、目标跟踪以及目标再截获和跟踪;给出某次飞行试验的距离与距离速度跟踪结果,跟踪状态良好,可满足靶场试验对测量雷达的精度要求。
Digital auto range tracking unit of the radar system use in shooting range was designed, two rank α-β filter han been adopted. It has some function such as multi-target tracking, range ambiguity resolving and blind range zone avoiding compere with regular radar system. The assistant tracking loop and delay interpolation unit were employed to achieve the target range credible high precision tracking. The results of certain fly testing range and velocity indicate its performance is better and measure precision was satisfied the request of shooting trial.
