Abstract
THE OBJECTIVE IS TO IDENTIFY METHODOLOGIES FOR DETERMINING THE OPTIMUM RADIALS AND DEPTHS FOR WHICH RANGE-DEPENDENT PROPAGATION LOSS CALCULATIONS ARE TO BE PERFORMED. THIS OBJECTIVE WILL BE ACHIEVED BY FIRST DEFINING REALISTIC ENVIRONMENTS UPON WHICH TO BASE THE ANALYSIS. FOLLOWING ENVIRONMENT SELECTION, RANGE-DEPENDENT PROPLOSS MODELS WILL BE RUN USING FINE MESH POINTS IN DEPTH AND ANGLE, AND OUTPUT DATA WILL BE STORED SUCH THAT PLOTS CAN BE MADE FOR VARIOUS CROSS SECTIONS OF THE FOUR DIMENSIONAL SPACE (PROPLOSS, RANGE, AZIMUTH, AND DEPTH). FOR EACH OF THE MULTIPLE RUNS, A SINGLE INDEPENDENT VARIABLE WILL VARY WHILE THE OTHERS ARE HELD CONSTANT. A COMPARISON OF PLOT BREAK POINTS WILL INDICATE THE SENSITIVITY OF VARYING EACH OF THE INDEPENDENT VARIABLES ON PROPLOSS. FROM THIS ANALYSIS, A SET OF "RULES" WILL BE DEVELOPED; THESE RULES WILL FORM THE BASIS FOR ESTABLISHING POSSIBLE METHODOLOGIES FOR DETERMINING OPTIMUM RADIALS AND DEPTHS.
