合成孔径声纳系统在海底掩埋电缆探测中的应用研究

The Application and Researchs of Synthetic Aperture Sonar System in Submarine Buried Cable Detection

随着海洋经济的迅速发展,海域使用开发活动日益频繁,海底已建掩埋电缆的探测尤为重要。该文以海底排污管道敷设工程为例,在管道敷设前,对该管道路由沿线周围进行了已建海底掩埋电缆准确位置调查。工程采用GPS定位系统、合成孔径声纳和磁力仪系统组合进行海底电缆探测,进一步证实了低频合成孔径声纳对海底掩埋电缆探测具有效率高、图像连续性好的特点。结果表明了该方法对海底掩埋目标物探测有较高的适用性,其船舷固定安装方式,有效减少了换能器与GPS偏移误差,能够有效提高目标位置精度。

With the rapid development of marine economy,the use and development of sea areas are becoming more and more frequent,and the detection of buried cables on the seabed is particularly important.In this paper,the submarine sewage pipeline laying project is taken as an example.Before the pipeline laying,the exact location of the buried submarine cables along the pipeline route is investigated.The project adopts the combination of GPS positioning system,synthetic aperture sonar and magnetometer system for submarine cable detection,which further proves that low frequency synthetic aperture sonar has the characteristics of high efficiency and good image continuity for submarine buried cable detection.The results show that the method has high applicability for the detection of buried targets on the seabed.The fixed installation on the ship side can effectively reduce the offset error between the transducer and GPS,and can effectively improve the target position accuracy.
