ASW TARGETING SOLUTION INTEGRATION

THE OBJECTIVE OF THIS PROJECT IS TO DEVELOP AN APPROACH TO THE GENERATION OF A "BEST" RANGE/SOLUTION ESTIMATE BASED ON ALL THE DIVERSE DATA AND SOLUTIONS THAT ARE AVAILABLE TO THE SUBMARINE COMBAT CONTROL SYSTEM. AN EXISTING PROTOTYPE SOLUTION INTEGRATION SYSTEM WILL SERVE AS THE BASELINE FOR THIS EFFORT. THE APPROACH TAKEN TO DESIGN THIS PROTOTYPE HAS BEEN TO USE THE UNIFYING MATHEMATICAL FRAMEWORK DERIVED FROM KALMAN FILTER THEORY TO GENERATE A SINGLE, INTEGRATED, STATISTICALLY ACCURATE RANGE/SOLUTION ESTIMATE. THIS PROCEDURE PROVIDES ESTIMATES THAT ARE MORE STABLE AND MORE ACCURATE THAN THOSE DERIVED FROM HEURISTIC MEANS. THE BASELINE SOLUTION INTEGRATION SYSTEM CAN PROCESS FIXES, BEARING REPORTS, FULL-STATE REPORTS, AND MATE SOLUTIONS. THE SYSTEM INCLUDES A STATISTICAL TRACKER THAT INCORPORATES BOTH A CONSTANT COURSE AND SPEED MOTION MODEL AND A MANEUVERING TARGET MOTION MODEL. IT ALSO INCLUDES A DATA MANAGER THAT CONTROLS THE INPUT DATA TO ASSURE STATISTICAL INDEPENDENCE. IN THE PROPOSED STUDY, THIS BASELINE WILL BE EXTENDED TO: GENERATE SOLUTION QUALITY ESTIMATES FOR OTHER TNA ALGORITHMS; SELECT DATA AND SOLUTIONS TO BE INPUT TO THE TRACKER BASED ON SOLUTION QUALITY AND STATISTICAL INDEPENDENCE; AND GENERATE THE OPTIMAL RANGE/SOLUTION ESTIMATE.
