机动目标跟踪的改进自适应滤波算法研究

摘要

In order to effectively achieve tracking the maneuvering target, based on Adaptive Filtering algorithm (Referred to as AF), an Improved Adaptive Filtering algorithm (Referred to as IAF) is proposed. The improved algorithm takes the maneuver target's system error as the random noise, and adjusts the acceleration variance adaptively. The advantages of the Improved Adaptive Filtering algorithm include simple in computation, tracking accuracy and so on.%为了更好地实现机动目标跟踪,在标准自适应滤波算法(Adaptive Filtering algorithm,简称AF)的基础上,提出了改进的自适应滤波算法(Improved Adaptive Filtering algorithm,简称IAF).该算法将机动目标的系统误差做为随机噪声,并对加速度方差进行自适应调整.改进的自适应滤波算法具有计算简单、跟踪精度高等优点.
