Abstract

Major limitations exist in using conventional sonar analysis techniques to predict system performance. Insensitivity of these analysis procedures to signal phase, time delay and spatial effects may be of major concern. The Coherent Acoustic Target and Environment Model (CATEM) is designed to efficiently and accurately predict system performance. The model processes, in a digital manner, the signals that are seen by a sonar located on a moving platform. Program architecture and methods used there- in to simulate the signals that emanate from different acoustic sources are discussed. Examples of the simulated sonar system outputs are given that can be compared to actual system performance.
