INTERDISCIPLINARY APPLICATIONS OF DIGITAL SIMULATION-COMPUTATIONAL FLUID DYNAMICS AND RADAR CROSS-SECTION

COMMON TECHNOLOGY CAN BE APPLIED TO THE DIGITAL SIMULATION OF FLOW OVER AERODYNAMIC CONFIGURATIONS AND TO THE CALCULATION OF RADAR CROSS-SECTION. NUMERICAL SOLUTION OF MAXWELL'S EQUATIONS CAN BE ACHIEVED USING THE SAME GRID, DATA BASE AND NUMERICAL METHOD EMPLOYED IN COMPUTATIONAL FLUID DYNAMICS. APPLICATION OF THESE ELEMENTS FROM CFD TO THE CALCULATION OF RCS OF SIMPLE BODIES IS PROPOSED IN THIS EFFORT. VALIDATION OF THE APPROACH IS ACHIEVED BY COMPARISION OF COMPUTED RESULTS TO KNOWN ANALYTICAL SOLUTIONS. THE ULTIMATE GOAL OF THIS PROGRAM IS TO SIMULTANEOUSLY SOLVE FOR THE FLOWFIELD AND RADAR CROSS-SECTION FOR A FLIGHT VEHICLE.
