Applied Physical Sciences Corp. proposes to develop a Marine Mammal Mitigation Miniature Acoustic Detection Subsystem (MADS) for the AN/SSQ-125 active source sonobuoy or similar system. MADS will consist of a miniature high-frequency active sonar array for detection and tracking of marine mammals within a nominal 300-m standoff distance from the high-power sonobuoy source. An initial design and performance predictions will be developed in the phase I base effort. A section of the receive array will be fabricated and tested in the phase I option. Phase II will demonstrate an autonomous detection system with a larger form factor and phase III will fully integrate MADS into the AN/SSQ-125 or other target sonobuoy. The designer and eventual manufacturer of the AN/SSQ-125, Ultra Electronics Undersea Sensor Systems, Inc., will provide support in phases I and II and is the phase III transition partner.
