A high fidelity front end simulation system is proposed using proven and planned technology to minimize development risk and cost. The All World Environment Simulation (AWESIM) technology is used to provide high fidelity simulation. AWESIM technology is proven, modular and scalable. By coupling… More

This effort will establish the baseline design of an advanced sonar simulator/stimulator suite for current and future systems with fidelity comparable with recorded at-sea data. This effort will bring together existing simulator designs with design changes or extensions to provide high fidelity… More

Spread spectrum signals have been successfully employed for many years in communications systems to transmit digital information when there is a need to combat the detrimental effects arising from various types of interference. More recently they have also been effectively employed in Low… More

The Anti-Submarine Warfare (ASW) capabilities of surface combatants, often operating in carrier or expeditionary strike groups, rely heavily on active sonar for detection due to the quieting of adversary submarines. These combatants have full knowledge of their own transmissions however; they employ… More
