Abstract: Applied Physical Sciences as the prime contractor and Undersea Sensor Systems, Inc. as the subcontractor propose an innovative approach to develop an air-deployed sonobuoy system having an array gain of at least 24 dB. The approach involves an array of subminiature vector sensors coupled to sophisticated in-buoy signal processing algorithms designed to provide the requisite data compression so that the bandwidth of the telemetry up-link is not compromised. The proposed effort comprises a series of analytical and numerical evaluations and trade studies that will culminate into a notional sonobuoy system at the end of the Phase I effort.
Benefits: The proposed innovation represents an order-of-magnitude improvement over the state-of-the-art in passive low frequency sonobuoy systems like the AN/SSQ-101 ADAR.
