Abstract

The Continuous Active Sonar (CAS) program is a NAVAIR project to demonstrate the feasibility of CAS operation for Anti-Submarine Warfare (ASW). The project is focused on multistatic distributed ASW sonar, supporting the localization-to-attack and maritime shield missions of ASW. In Phase I of this project, Signal Systems Corporation (SSC) demonstrated, using simulations, that a CAS variant of a Directional Command Activated Sonobuoy System (DICASS) may enhance performance for the localization to attack Anti-Submarine Warfare (ASW) mission. The Phase II objective is to show, using Navy standard system analysis tools and at-sea tests, better environmental compatibility, enhanced detection of strongly specular or glint type target reflectors and better energy efficiency due to lower SPL operation. These improvements should result in improved tracking and maritime shield defense.
