用于纯方位机动目标跟踪的机动探测法

假设目标在某时刻发生折线机动,并且目标在机动前后都是做匀速直线运动。所提出的机动探测算法通过探测这种变化得到探测时刻。这种算法是基于对方位预测误差的均值变化进行分析的。然后估计出目标机动时刻,并从机动时刻起重新设置滤波器,估计出目标机动后的运动参数。典型的机动TMA态势仿真结果表明,该算法对于一般的目标折线机动可以有效地进行跟踪。

Maneuver Detecting Algorithm Used for Bearings-only Maneuver Target Tracking

The target is assumed at a random instant to switch between two linear motions by changing its course or velocity. The proposed maneuver detecting algorithm detects the change and gets the detection time. The algorithm is based on a sequence of bearing prediction errors. Then it estimates the time of change and resets the filter to compute the target motion estimates up to detected time. The algorithm performance is illustrated in some representative TMA scenarios.
