Abstract

The various acoustic sonar systems are used for exploring ocean environments and target localization. Multi-beam sonar, synthetic aperture sonar, and array hydrophones are some good examples. When using such sonar systems the system motion is inevitable, thus one of their core processing algorithms are related to compensation of the sonar motion. In this paper a simulator for modeling underwater acoustic propagation channel is introduced. The simulator can be used for moving transmitting transducer array as well as moving hydrophone array. Its codes are written in m-script for using in Matlab program. Examples of estimated received signals shows that the simulator will be a useful tool for developing acoustic systems.
