基于雷达海面回波的水下潜艇非声探测

由于潜艇降噪技术的提高,使得传统的声纳设备对水下潜艇的探测变得越来越困难.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.

Research on Non-acoustic Detection for Underwater Submarine based on Radar Sea Surface Echo

As the improvement of submarine denoise technique, it turns more and more difficult to detect a submarine through traditional sonar equipments. This article puts forward a detection method based on distinctive radar signals of sea surface echo directly. 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.coefficient
