Abstract
YIELECTRIC COATINGS ON VEHICLES CAN ALTER THEIR RADAR IMAGE SIGNIFICANTLY. THIS PROPOSAL IS DIRECTED TO DETERMINING NUMERICALLY THE REFLECTIVITY FOR AN OBJECT COVERED BY A DIELECTRIC LAYER. A CALCULATION WILL BE DONE USING BASIC PHYSICAL PRINCIPLES TO DEFINE THE THEORETICAL BOUNDARY VALUE PROBLEM FOR THE DIELECTRIC LAYER. THE SOLUTION TO THIS PROBLEM WILL BE OBTAINED NUMERICALLY USING MATRIX INVERSIO AS PART OF A COMPUTER PROGRAM WHICH ALSO PRESENTS THE RESULTS GRAPHICALLY. THE PHASE I PROBLEM WILL BE LIMITED TO REFLEC TION FROM PLANES. EXTENSION OF THE PROBLEM TO OTHER GEOMETRIES WILL BE INITIATED IN PHASE II. A TRANSIENT SOLUTION TO THE BOUNDARY VALUE PROBLEM WILL BE OBTAINED IN ORDERTO SYNTHESIZE BOTH THE SHAPE AND THE AMPLITUDE OF THE REFLECTED IMPULSES. THE DIVERSITY OF INFOR MATION DETERMINED FROM THE SOLUTION TO THE PROBLEM WILL BE PRESENTED IN A CONCISE, GRAPHICAL FORM TO ENCOURAGE AN INTUITIVE RESPONSE TO SUCH VARIATIONS AS THE ATTITUDE OF THE OBJECT, OR THE FREQUENCY SPECTRUM OF THE MICROWAVE IMPULSE. PROGRAMS AND GRAPHICAL TECHNIQUES DEVELOPED FOR THE PLANE, DIELECTRICALLY CLAD, METALLIC SURFACE WILL BE APPLIED TO MORE COMPLEX OBJECTS IN PHASE II.
