摘　　要：针对已有杂波环境中机动多目标跟踪算法运算量大的不足,提出了一种基于有机动检测和机动转稳态判断的自适应α-β滤波和改进的模糊数据关联的新方法,并利用滤波过程中的机动指标实时地调整波门的大小。该方法计算量小,易于工程实现。Monte Carlo仿真结果表明了该方法良好的跟踪性能。To reduce the complexity of some algorithms of tracking multiple maneuvering targets in clutter, a new method is proposed based on improved FDA and adaptive α-β filter which includes maneuver detection and judgment of maneuver-to-steady state conversion, using the maneuver index to adjust the size of the wave gate adaptively. This method has low computational load and is easy to be realized in TWS systems. Th＇e Monte Carlo simulation results orove its good tracking peribrmance.
