Abstract. Side scan sonar (SSS) is an important mapping tool in underwear imaging
system. This paper provides sufficient information on SSS design. SSS is
known for very high quality, high resolution, ocean bottom imaging. It is
able to rapidly survey large ocean areas for bottom and suspended sea-mines
or other kinds of threats. Another operational aspect of these systems is
that they allow autonomous underwater vehicles (AUVs) to conduct operations,
mostly in shallow water and near land. It produces a representation in image
form of the seabed; however, no closed form analytic expression or direct
modeling technique exists to represent this complex process. In this paper
the basic principle is presented for a model for the simulation of SSS,
which produces as its output a qualitative image of the form generated by
the actual SSS. The model considers the underlying physical processes
including the effects of the refractive water medium, the scattering from
the seabed and the transducer motion and directivity characteristics.
Further, this work concerns the design and analysis of SSS via MATLAB
simulation in order to satisfy the operational requirements. Moreover, this
research has tried to indicate the various problems that may arise when a
SSS operates in its near-field region and suggests certain solutions. The
active sonar equation and its factors were explained and were evaluated.
