Adaptive Filtering and Estimating Algorithm Based on α-β Filter

针对目标运动量测信息的特点,通过分析α-β滤波算法,指出该算法常增益的特点影响其对机动目标的跟踪效果。为了克服这个缺点,给出了一种新的目标运动信息滤波和估计的自适应算法,该算法可直接利用构造的函数关系自适应调整α,β的值。仿真结果表明,该自适应α-β滤波算法对目标运动信息的滤波和估计具有较好的性能。

According to the measuring characteristics ter algorithm, its fiequent plus feature influences effect of adaptive filtering estimating al tion, the algorithm can adjust the gorl flit of maneuvering target and analysis of α-β filtracking maneuvering target. Thus, a new self- thm was advanced to improve the effect. Aided by the created func- ering parameter α-β on line. The simulation result shows that the self-adaptive estimating algorithm has a preferable filtering performance
