Abstract
NEXT GENERATION HPM SUSCEPTIBILITY TESTS WILL INVOLVE SIGNIFICANTLY LARGER TEST OBJECTS AND ANECHOIC CHAMBERS THAN THOSE PRESENTLY USED. WHILE ACCEPTABLE TEST FIDELITY REQUIRES ACCURATE SIMULATION OF BATTLEFIELD-LIKE IRRADIATION CONDITIONS, ITS ACHIEVEMENT, PARTICULARLY UNIFORM PLANE-WAVE ILLUMINATION, BECOMES SUBSTANTIALLY MORE DIFFICULT FOR LARGE, COMPLEX TARGETS, I.E., THOSE WITH EXTENDED CROSS-SECTIONS AND MULTIPLE POES, SUCH AS AIRCRAFT. THESE PROBLEMS, EXACERBATED BY LIMITED ANTENNA-TARGET SEPARATION AND POOR LOW FREQUENCY ABSORBER PERFORMANCE, MUST BE ADDRESSED DAILY BY TEST PERSONNEL. WE PROPOSE TO DEVELOP AN INNOVATIVE, PC-BASED PROGRAM WHICH WILL INCORPORATE COMPARTMENTALIZED, SELF-CONTAINED ROUTINES FOR NEAR-FIELD ANTENNA RADIATION, TEST OBJECT SCATTERING, ABSORBER SCATTERING, AND SITUATION ANALYSIS. BY USING A NOVEL TECHNIQUE INVOLVING FAST LOOK-UP IN A PRE-COMPUTED LIBRARY/DATABASE, THE PROBLEM'S MOST TIME-INTENSIVE PART, TEST-OBJECT SCATTERING, IS GREATLY SIMPLIFIED, THEREBY ALLOWING EXTRAORDINARILY RAPID DETERMINATION OF THE FIDELITY OF A BROAD CLASS OF TESTS. TEST FIDELITY WILL BE EVALUATED AS A FUNCTION OF: (1) RELEVANT HPM SOURCE AND ANTENNA PARAMETERS; (2) PLACEMENT, ORIENTATION, AND NATURE OF THE TEST OBJECT; AND (3) CHARACTERISTICS OF ABSORBING MATERIAL LINING CHAMBER WALLS. USING CODE-PRODUCED FIGURES-OF-MERIT, TEST CONDUCT PERSONNEL WILL, FOR THE FIRST TIME, MONITOR AND QUANTIFY ACCEPTABILITY OF IN-PROCESS TESTS IN REAL TIME.
