Sonar Array Aperture Synthesis as a Foundation for Mobile Surveillance Sonar Systems
Abstract
The paper analyzes the most effective aperture synthesis methods in hydroacoustics. A synthesis method for wide-band signals is suggested. A SynApp program developed for comparative analysis of different methods is described. The results of an experimental study with test signals (generated by the program) and real signals (obtained from a real towed array) are presented. Aperture synthesis availability in hydroacoustics is concluded.
