Abstract

The need to identify and monitor the target by taking active measurements before it gets close enough to attack has grown due to advancements in marine technology. As underwater vehicular technology continues to progress, there is an increasing interest in using U A V s for target tracking behavior. Numerous methods have been put out to improve tracking performance despite the challenges in harsh underwater environment. SONAR has replaced the radiofrequency signals with the acoustic array signals which is the most modern way of communication. This study demonstrates how to model targets in an active monostatic sonar for multipath propagation paths between source and targets. An isotropic projector array and a single hydrophone unit make up the sonar system for this research work. This paper implemented the form of the projector array which is spherical, and hydrophone receives the backscattered signals. Both direct and multipath contributions are present in the signals that were received on arrival from both targets and are plotted in MATLAB.
