基于恒虚警检测的图像声纳目标跟踪

Image sonar target tracking based on constant false alarm detection

摘要:

无人化，智能化的目标探测与跟踪是未来水下探测的必然趋势。针对水下移动小目标，通过声纳接收的角度与距离二维信息，提出了一套自动跟踪方法。首先，对图像声纳进行恒虚警处理，同时引入时域参量，通过在门限计算中增加之前时间的权重，抑制位置恒定的静态强背景干扰，最后，基于空间上目标的连续运动，提出了小目标的自动跟踪算法。湖试数据实验处理表明，该方法能有效抑制干扰，实现水下小目标的自动探测跟踪。

Abstract:

Unmanned and intelligent target detection and tracking is the inevitable trend of underwater exploration in the future. An automatic tracking method based on Angle and distance information received by sonar is proposed for small moving underwater targets. Firstly, the image sonar is treated with constant false alarm, and the time-domain parameters are introduced to suppress the static strong background interference with constant position. Finally, based on the continuous motion of the target in space, the automatic tracking algorithm of small target is proposed. Experimental processing of lake test data shows that this method can effectively suppress interference and realize automatic detection and tracking of small underwater targets.
