Net-Centric Data Fusion (NCDF) for Undersea Warfare Decision Support System (USW-DSS) and SSQ-89A(V)15 Torpedo Defense Functional Segment (TDFS)

NCDF is a low-cost system solution (straightforward integration of mature, extensively tested components) providing:

  • An accurate and fused Common Tactical Picture (CTP), utilizing all available networked sensor data
  • An automated multi-sensor system with a high probability of torpedo attack detection (PD) and a low false alarm rate (FAR)

NCDF, CTAM and TOAM components have been integrated into Undersea Warfare Decision Support System (USW-DSS) Build 2 in order to provide automatically generated cross-platform track association recommendations and a common tactical picture.  NCDF, CTAM and BIE components are being integrated into a SQQ-89A(V)15 ACB-13 in order to provide more accurate torpedo alerts and a torpedo defense Situational Awareness picture
