摘要
α-β滤波器是一种在雷达数据处理中常用的跟踪滤波器,其中系数的选择是决定滤波器性能优劣的关键。在充分理解α-β滤波器算法的实质的基础上,利用一双曲函数的简单性质,提出了一种具有工程实践意义的适用于机动目标跟踪的α-β算法,该算法结构简单、运算量小、易于工程实现。文中介绍了其基本原理,给出了其理论根据,并对算法进行了仿真,在仿真中与其他工程中常用的算法相比较,仿真结果验证了算法对机动目标跟踪的有效性。
α-β algorithm is a kind of filter often used in radar data processor. Its performance depends on the its coefficient selection. In this paper, an adaptive α-β algorithm that could be put into practice in engineering is presented. It is characterized by simple structure, less computation, and easy to be realized, Its principle and theoretical evidence are also introduced. Comparisons with other algorithms used in engineering are made by means of simulation tests, and the results prove its efficiency.
