The progress of researches on non-acoustic detection for submarine wake is presented in the paper.
伯努利“水丘”、开尔文尾流、涡尾迹、内波尾迹都起源于潜艇水动力学 ,对于潜艇的非声探测具有重要的应用意义。
Because turbulence and wake caused by a submarine\'s underwater movement on certain sea state and submerged depth conditions,result in abnormal radar backscattering coefficient of ocean surface,Computer experiment is done by this detection method,and the results are analyzed,Thus this paper will provide valuable help for studying non-acoustic detection for submarine.
根据水下潜艇在运动时形成的尾流、尾迹,引起海面雷达后向散射系数发生"异常"这一特征,提出了一种直接利用雷达海面回波信号来探测水下潜艇的方法,并利用计算机仿真实验对此探测方法的实验结果进行了分析评估,为研究潜艇的非声探测提供了有价值的参考。
