一种合作目标轨迹的处理方法

A processing method for the track of cooperative target

在使用声图测量的方法对扫描区域内的目标进行定位时,由于声图定位的局限性,使得目标的定位轨迹出现一定的误差。为了有效减小定位误差,提出了采用"圆筛"和α-β滤波相结合的方法处理目标轨迹。由实验数据处理证明,此方法可以有效减小目标航迹抖动,并且可以实现目标轨迹的平稳过阵。

In the using of underwater acoustic image measurement（UAIM） method to locate target, due to the limitations of UAIM, making the track of the target a certain error. In order to reduce the error effectively, this paper proposes a method of combining ＂round filter＂ and α-β filter to approach the track of the target, The experimental data processing proves that this way can effectively reduce the track jitter, and can also achieves a smooth track over the array.
