Abstract


This paper introduces a new beamforming and received data post-processing method for forward-looking sonar applications with limited number of array elements. Applications like Sidescan or Forward Looking Sonars, used for area efficient sea floor imaging, collect large amount of raw data, which allows us to do both imagery and additional data processing. Moreover, object localization improvement could be accomplished by the post-processing of the received information collected with digital beamforming and beam focusing. Test results illustrate the efficiency of the proposed post-processing algorithms in terms of angular aperture and target detection.
