摘　　要：给出了一种基于动力学模型的积分滤波机动检测方法，通过滤波时对机动时间、机动强度和滤波残差的实时统计，可以准确识别目标的机动状态，并自适应调整滤波参数，保证滤波的精度。对野值具有很强的抑制能力，能够在很大程度上减小虚警的概率。该方法适合靶场对高机动弹道的机动检测。A method of maneuver detection by integral filtering based on the dynamic model is proposed in this paper. The object maneuver state can be identified exactly through the real-time statistics of maneuver time, maneuver intensity and filtering residual when filtering. In the mean time, the filtering parameters can be adjusted adaptively to guarantee the filtering precision. This method holds powerful ability to restrain the data outlier so that it can decrease the false alarm probability evidently. It is suitable for maneuver detection of high-dynamic trajectory.
