Abstract :
An indigenously developed Buried Object Detection SONAR (BODS) for finding targets in the seabed is described in this paper. The important features of BODS are wide bandwidth (2-24 kHz), light weight projector (21 kg) and computer based real time signal processing. The results from experiments at shallow waters to detect seabed boundary layer and targets like metal plate and concrete blocks, are also presented in this paper. It is seen that sediment layers and the targets are distinguishable in the BODS image.
