为了解决处理速度与跟踪性能之间的矛盾,提出一种带伪加速度修正的跟踪算法.该算法利用球坐标系下距离、方位、俯仰的测量误差的不相关性,引入三个方向的伪加速度,建立目标运动模型、测量模型.同时结合选取最佳跟踪波门,实现了对空中机动目标的实时跟踪.与传统的自适应卡尔曼滤波跟踪算法相比,在减少计算量的同时,提高了机动目标的跟踪精度.仿真和实验结果表明,该算法对空中机动目标具有良好的跟踪性能,工程实用性强.

In order to solve the contradiction between processing velocity and tracking performance,a tracking algorithm with pseudo acceleration correction is proposed. By utilizing the incoherence of measuring error in range,distance,elevation un?der spherical coordinates,the pseudo acceleration in three directions is imported in the tracking slgorithm to establish target mo?tion model and measurement model. With selection of the optimal tracking gate,the real?time tracking of maneuvering targets was realized. Comparing with the traditional adaptive Calman filtering tracking algorithm,the arithmetic reduced computation and improved the tracking accuracy. Simulation and experiment indicate that the tracking algorithm has high tracking perfor?mance in mobile target tracking in the air and is effective in engineesing project utility.
