机动目标跟踪中一种机动频率和方差自适应滤波算法
One Maneuvering Frequency and the Variance Adaptive Filtering Algorithm for Maneuvering Target Tracking
摘要
Abstract
The approach of tracking maneuvering targets based on the“Current”Statistical (CS) model is widely used. The method needs to preset the maneuvering frequency and the maximum acceleration based on experience. In practice, the preset values are often not consistent with the actual moving state of targets and result in larger tracking errors. To tackle the problem, we initially deduce a self-adapting maneuvering frequency algorithm from the discrete-state equation of the CS model. Then, an improved self-adapting acceleration covariance algorithm is presented. Simulation results show that, by using the self-adapting maneuvering frequency algorithm and the improved self-adapting acceleration covariance algorithm to track targets simultaneously, we can improve the ability to self-adapt to the fluctuation of the moving state. The tracking accuracy is also improved, and the convergence speed of the algorithm is relatively quick.关键词
