Abstract: |
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. |
