Abstract: In this SBIR project Wagner Associates will develop innovative: (1) hull array passive signal processing (providing more accurate bearing, narrowband frequency, and signal-to-noise (SNR) data), (2) passive state estimation, (3) torpedo launch platform localization, and (4) enhanced data fusion, classification, and alerting algorithms and software, referred to in this proposal as Innovative Passive Processing (IPP). These IPP algorithms will significantly advance the Passive Tracking and Detection, Classification, and Localization (DCL) state-of-the-art and result in much improved forward sector TD for ships with a passive hull array such as U.S. DDGs and CGs with the SQQ-8A(V)15 (in both passive only and active plus passive modes).
Benefits: IPP provides a significant increase in Torpedo Defense Functional Segment (TDFS) military utility since it will detect, classify, and localize quiet electric and loud thermal torpedoes at tactically significant ranges, getting TDFS much closer to its goal of alerting at tactically significant ranges against forward sector torpedoes while still having a high probability of alerting (PA) on a threat torpedo attack, and a near zero false alarm rate (FAR). IPP will also resolve torpedo salvos much more effectively than current signal processing algorithms and accurately estimate the location of the torpedo launch platform.
