In this paper, we describe the SAMDIS complete solution of high resolution SAS multi-aspect and SAS interferometry, which was tested during first sea trials. It provides SAS bathymetry maps at high-resolution and enhances classification probability in non-flat sea bottom configuration. Furthermore, the SAMDIS sonar is equipped with an interferometric antenna, similar to the imaging antenna. ![]() The diversity of aspect angles associated with high resolution SAS image is mandatory for Mine Counter Measure applications notably for classification. In order to change the aspect angle of a scene without wasting time in revisiting the place, the SAMDIS sonar processes SAS imagery under different view angles simultaneously. Thales Underwater Systems developed a new sonar, named SAMDIS (Synthetic Aperture Mine Detection and Imaging System), a compact system which can be easily mounted on AUV and delivers high-resolution underwater SAS imagery. They equip towed bodies as well as Autonomous Underwater Vehicles (AUV), surveying seabed in total autonomy. Synthetic Aperture Sonars (SAS) image sea floor at high resolution, independently of range.
