Airborne Multistatic Anti-Submarine Warfare Operator Target Detection and Discrimination System Workload Reduction

Signal Systems Corporation (SSC) is developing a Multistatic Operator Target Search and Discrimination Aide (MOTSDA) that enables operators to exploit the increased search detection capabilities of future Air ASW designs without workload increases. Using MOTSDA, operators will focus on promising alerts and regions of high interest that are generated by new automatic target discrimination techniques. MOTSDA provides a closed loop search and target alertment capability that works across wide geographic areas independent of operator fatigue and display. MOTSDA will improve active target discrimination by using a new classification feature. Key innovations include an automatic snippet confirmation detector that uses a short number of pings to confirm a target’s presence and discriminate it from harsh clutter. A second innovation enables improved target classification in harsh clutter conditions when the target aspect averaged probability of detection is low. In Phase II, SSC will continue algorithm development using at-sea data sets, support Step 1 and 2 Advanced Processor Build evaluation of our Automatic Snippet Confirmation algorithm, provide a Step 1 briefing for our new classification feature, develop a real-time MOTSDA prototype processor and display, and evaluate the prototype in an at-sea closed loop test.
