三维合成孔径声呐在海底掩埋目标探查中的应用现状与展望

为提高我国海底掩埋目标的探查技术，以适应不断发展的探测需求，文章综述了现有三维合成孔径声呐在海底掩埋目标探查中的应用现状，并对关键技术的发展方向进行了展望。结果表明:尽管三维合成孔径声呐在海底掩埋目标探查中具有较大的技术优势，但是由于技术难度大、复杂程度高，可提供成熟商用设备的单位仅有两家，中科探海研发的三维合成孔径声呐系统多项核心技术指标领先。运动误差估计和补偿技术，掩埋目标特征提取和识别分类算法，多通道大规模数据并行处理算法等关键技术将成为三维合成孔径声呐系统未来的发展方向。

The Applications and Prospect of 3D Synthetic Aperture Sonar System in Buried Targets Detection

For the purpose of improving the domestic technology on buried targets detection,and matching increasing demands of submarine detection,this paper reviewed the applications of 3D synthetic aperture sonar system on buried targets detection,and prospected the future direction of the core technologies.It was found that: there are only two corporations providing developed 3D SAS due to the high complexity and difficulty in designing and implementation,despite of its great advantages in buried targets detection; many parameters of the 3D SAS produced by T-SEA Marine Technology Co.,Ltd.are ahead of the competitor; motion error estimation and compensation,buried targets feature extraction and classification algorithm,and multi-channel parallel processing algorithm for large-scale data would be the future direction of 3D SAS.
