High Altitude Non-Acoustic Antisubmarine Warfare (ASW)

Current ASW sensors rely either on active transmissions or close passive detection from low altitude or in water. Active transmissions can be detected and countermeasured, and platforms operating from low altitude can be directly heard or seen also allowing fairly easy countermeasures or evasion. The intent of this proposal is provide the instrumentation and data necessary to quantify the polarization requirements of future passive multi or hyper spectral system utilized for high altitude ASW missions.
