本文从工程应用的角度出开,通过模拟实验,分析比较了卡尔曼滤波器和最小二乘α—β滤波器在边搜索边跟踪数据处理系统中的应用。从跟踪方程、座标系的选择和目标机动检测器三个方面讨论了滤波器的结构型式。试图说明:当选用rθ-xy双座标体制和适当的机动检测后,最小二乘α—β滤波器与卡尔曼滤波器相比较,在精度上相近,而计算量少1/2左右。它是单雷达站边跟踪边搜索系统中的一种适用的滤波器型式。最后,简单地介绍了飞行试验结果。
From the perspective of engineering application, this paper analyzes and compares the applications of Kalman filter and least-squares α-β filter in the tracking data processing system of side search through simulation experiments. The structure of the filter is discussed from three aspects: tracking equation, the choice of coordinate system and the target detector. Attempting to explain: When using the rθ-xy dual-coordinate system and the appropriate maneuvering detection, the least-squares α-β filter is similar in accuracy to the Kalman filter, but the calculation is less than 1/2. It is a suitable type of filter used in the search system of a single radar station. Finally, a brief introduction to the flight test results.
