Underwater acoustic channel models have been studied in the context of communication and
sonar applications. Acoustic propagation channel in an underwater environment exhibits multipath,
time-variability and Doppler eects. In this thesis, multipath fading channel models,
underwater physical properties and sound propagation characteristics are studied. An underwater
channel model for sonar applications is proposed. In the proposed model, the physical
characteristics of underwater environment are considered in a comprehensive manner. Experiments
/simulations were carried out using real-life data. Model parameters are estimated for a
specific location, scenario and physical conditions. The channel response is approximated by
fitting the model output to the recorded data. The optimization and estimation are conducted
in frequency domain using Mean Square Error criterion.
