DEVELOPING SEARCH PLANNING METHODS FOR OPTIMIZING ASYMMETRICAL DETECTION PERFORMANCE

THIS PROPOSAL ADDRESSES THE PROBLEM OF SEARCH PLANNING FOR ASYMMETRICAL DETECTION PERFORMANCE THROUGH A GENERALIZATION OF THE CONCEPT OF SWEPT AREA TO A "SWEPT AREA DISTRIBUTION." IN THIS APPROACH, SEARCH EFFECTIVENESS IS NOT MODELED BY A SINGLE NUMBER, SWEPT AREA, BUT RATHER BY A DISTRIBUTION THAT MEASURES THE LOCAL SEARCH EFFORT AT EACH POINT. THE INTEGRAL OF THE SWEPT AREA DISTRIBUTION IS THE USUAL SWEPT AREA. THIS APPROACH ALLOWS ASYMMETRY IN BOTH DEPTH AND DIRECTION TO BE MODELED. THE PROPOSED WORK HAS THREE MAIN OBJECTIVES:DETECTION MODELING--TO DEVELOP A SIMPLE BUT ACCURATE MODEL FOR ASYMMETRIC DETECTION PERFORMANCE. SEARCH PLANNING METHODOLOGY--TO GENERALIZE THE STANDARD SWEPT AREA SEARCH PLANNING TOOLS-USING THE SWEPT AREA DISTRIBUTION. TEST BED--TO CONSTRUCT A DEMONSTRATION TEST BED TO EVALUATE THE TACTICAL UTILITY AND TO DEMONSTRATE THE COMPUTATIONAL FEASIBILITY OF THE PROPOSED APPROACH. TAKEN TOGETHER, THESE THREE OBJECTIVES SHOULD PROVIDE A CLEAR DEMONSTRATION OF THE FEASIBILITY OF EMPLOYING THE SWEPT AREA DISTRIBUTION CONCEPT IN ASW SEARCH PLANNING.
