This paper is concerned with the problem of recognition of objects laying on the seabed and presented on echosounder images. Considering that high resolution echosounder system provides acoustic images of high-quality, this research have been interested in shallow water investigations for underwater objects. This work presented recent detection algorithms for coral reef, seagrass, and seabed using signal processing. Acoustic reflectivity and backscatter strength of coral reef were higher than seagrass. The lifeform of coral reef had different acoustic intensity value.
