Sonar signal processing based on COTS components

This paper addresses the application of commercial off-the-shelf (COTS) components to sonar signal processing. The Active Towed Array Sonar System (ACTAS) is introduced, the COTS components used for setting up the signal processing are described, and key experiences with the use of COTS are illustrated. Furthermore, the main software components necessary for system set-up are described. CORBA is used for communication and data transfer between software components.
