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,通过固定位置的声呐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,对图像声呐进行恒虚警处理,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。之后,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。Unmanned and intelligent target detection and tracking is the inevitable trend of underwater exploration in the future.An automatic tracking method for small moving underwater targets is proposed based on angle and distance information received by fixed sonar.Firstly,the image sonar is processed with constant false alarm,the time-domain parameters are introduced,and the weight of previous time is added to the threshold calculation to suppress the static strong background interference with constant position.And then,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.
