摘要
α-β滤波方法常在武器系统中用于跟踪滤波。针对这一问题,作者探讨了如何确定该滤波器的优化参数问题,并与其它参选法进行了比较。本文还讨论了与参数优选相关的几个问题,比如相关波门尺寸的确定和有关自适应滤波的一些考虑。本文引入了一个叫做滤波方差折失比的概念作为标准来衡量滤波效果,引入嵌套率来评判波门的优劣。实验表明:经优化的α-β滤波器可以获得满意的效果,合适的波门选取可以保证高概率的目标录取和较低限度的测量噪声的影响。
α-β filter is often used to track objects in weapon systems. This paper describes how to determine the optimal parameter of this kind of filter, compares the performance of optimal α-β filter with other kinds of α-β filter. Some other problems related to optimal α-β filter, such as the size of the related window, self-adaptive filter, etc. are discussed. Rate of Filter Variance Loss (RFVL) is introduced as the criterion to estimate the performance of filters, and Rate of Coverage (RC) as that to evaluate the related window sizes. It is shown through experiments that good effect wouldbe obtained with the optimal α-β filter, and a proper choice of the related window size would be essential to obtain high detection probability and low measurement noise influence in target tracking.
