87-06: RADAR CROSS SECTION CALCULATIONS

IN PHASE I, A STUDY TO THIS PROPOSAL DESCRIBES A STUDY TO ESTABLISH TECHNICAL MERIT AND FEASIBILITY OF EXPANDING THE CURRENT SOLID MODELING VISUALIZATION ALGORITHMS, USED IN VIEWING OBJECTS ILLUMINATED BY LIGHT, TO VIEWING OBJECTS REPRESENTED BY THEIR UHF FREQUENCY RADIATION AND SCATTERING. THIS WOULD ALLOW A DISPLAY OF THE 3D RADAR CROSS SECTION WITH COLOR GRAPHICS REPRESENTING DIFFERING INTENSITY AND ELECTROMAGNETIC PROPERTIES. THE STUDY WOULD IDENTIFY THE IMPLEMENTATION SPECIFICATIONS OF REQUIRED SOFTWARE TO INCORPORATION OF MICROWAVE SPECTRA ELECTROMAGNETIC SOURCE; DEVELOP MORE EFFECTIVE BOUNDING METHODS FOR CALCULATING THE RAY-SURFACE INTERSECTION; IMPROVED BICUBIC SURFACE PATCHES; UHF REGIME BIDIRECTIONAL REFLECTANCE SURFACE COEFFICIENTS; SIMULATION OF A TIME DOMAIN PULSE STRIKE; CALCULATION AND DISPLAY OF THE BISTATIC SCATTERING MATRIX FOR OBLIQUE INCIDENCE. IN PHASE II THE DESIGN AND SPECIFICATIONS CREATED IN PHASE I WILL BE USED TO DEVELOP A DEDICATED MICRO (PC) OR MINICOMPUTER (80386, SUN, APOLLOR OR MICROVAX) WORKSTATION FOR THE INTERACTIVE MODELING AND DISPLAY OF 3D RADAR CROSS SECTIONS OF TARGETS.
