机动目标跟踪的改进自适应滤波算法研究

An Improved Adaptive Filtering Algorithm Research of Maneuvering Target Tracking

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 algo-rithm,简称AF)的基础上,提出了改进的自适应滤波算法(Improved Adaptive Filtering al-gorithm,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。

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.
