摘　　要：水下浅埋目标物的探测是水下考古和海洋探测的难点。梳理了现有水下浅埋目标物探测技术,认为传统水下掩埋物探测技术尚存不足,三维合成孔径声呐技术更具优势。通过对海底古沉船的实测,认为三维合成孔径声呐能够有效获得浅掩埋目标物三维结构状态、埋深情况和高分辨率图像等信息,可以更有效地实现对水下浅埋目标物的探测与精确识别。The detection of shallow buried objects is a difficult problem in underwater archaeology and marine survey.In this paper,the existing detection techniques of shallow buried objects under water are sorted out,and it is considered that the traditional detection techniques of buried objects under water have disadvantages,and three-dimensional synthetic aperture sonar technology is more advantageous.Through the measurement of ancient shipwrecks on the seabed,this paper believes that 3D synthetic aperture sonar can effectively obtain the information of three-dimensional structure,buried depth and high-resolution image of shallow buried objects,which can realize the detection and accurate identification of shallow buried objects more effectively.
