| 摘 要： | 为了改善声呐图像中存在大量杂波而导致目标跟踪困难,设备虚警率高的缺点,提出一种图像关联降噪算法。首先利用目标特性对静止目标进行剔除,之后利用目标运动的持续性和目标回波在连续多帧图像中的空间位置关联性,对随机噪声进行进一步滤除。仿真和试验数据验证,所提出的算法对于背景比较稳定的图像,降噪效率不低于95%。

| Abstract: | In order to solve the difficulty of tracking moving targets and the high false alarm rate resulting from the presence of clutter sonar image, a clutter suppression algorithm is proposed in this paper to remove the static target echo and meantime to filter the random noise by using the target''s temporal continuity and space relevancy. The algorithm is verified by simulation and experimental data processing, the noise reduction efficiency is no less than 95% for the image with stable background. |

| Keywords: | fixed installation sonar temporal continuity spatial neighborhood integral clutter suppression image relevancy |
