Underwater acoustic channel modeling using BELLHOP ray tracing method

In recent years, underwater acoustic technology has rapidly developed in the mean of civil and military usage. The majority of models in underwater communication undergo the following factors those are limited bandwidth, high attenuation, time varying, multipath propagation, dispersion of signal and slow rate signal transmission. In this study we have design a GUI to examine the behavior of an acoustic signal with transmission frequency band (9 K to 90 KHz) under the above mentioned factors. We have selected two different channels environments in Arabian Sea to show channel effect over an acoustic signal, BELLHOP tool is used to design underwater channel.
