Abstract
ASW PASSIVE SONAR SEARCH PLANNING CONSISTS OF TWO MAJOR AREAS: EMPLOYMENT OF THE SEARCHING PLATFORM (COURSE, SPEED, DEPTH, AND TRACK PLAN) AND SONAR SYSTEM LINEUP SELECTIONS. THESE TWO AREAS ARE INTERDEPENDENT, BUT THE DEGREE AND NATURE OF THE INTERACTION IS NOT WELL UNDERSTOOD. CURRENT SONAR LINEUP MODELS ARE STATIC IN NATURE AND DO NOT ADEQUATELY MODEL THE DYNAMIC ASPECTS OF THE SEARCH PROBLEM. IN ADDITION, DETECTION PERFORMANCE IS ASSUMED TO BE SYMMETRICAL. WE PROPOSE TO DEVELOP SEARCH PLANNING METHODS FOR OPTIMIZING ASYMMETRICALDETECTION PERFORMANCE BY COMPLETING THE FOLLOWING TASKS: TASK 1. DEVELOP A MATHEMATICAL MODEL OF THE SUBMARINE PASSIVE SONAR SEARCH OPTIMIZATION PROBLEM. TASK 2. DERIVE A MATHEMATICAL PROGRAMMING ALGORITHM FOR A SPECIFIC CASE OF THE SONAR LINEUP PROBLEM, AND TASK 3.COMPARE THE RESULTS FROM TASK 2 WITH A SEARCH SIMULATION MODEL CURRENTLY IN USE BY THE SUBMARINE FORCE.
