摘要
通过对复合控制在α-β滤波器中应用原理的分析,得出了在四维跟踪雷达系统中,距离跟踪回路可利用速度跟踪回路测量结果应用复合控制方法来减少跟踪高加速度目标时产生的动态滞后误差的重要结论,并提出了工程实现方法和应用该方法的具体步骤,通过仿真实验证明了该算法的有效性。实验数据表明,这种方法对于四维跟踪雷达是否需要利用测速回路输出改善测距回路性能具有重要的参考意义。
An analysis is made show the principle of the application of compound control in the α-β filter. An important conclusion is obtained, which is the distance track loop can use the results of velocity track loop to reduce the dynamic track error while tracking high acceleration target in the four-dimension track radar. A realization method for engineering is presented. In the end, the experimental results demonstrate the efficiency of this realization method. This method is of great significance to whether a four-dimension track radar needs using the output of the velocity track loop to improve the performance of the distance track loop.
