Some aspects of valid EMC testing of missiles
Abstract
Laboratory EM compatibility testing of missiles is discussed, with emphasis on the validity of near-zone sources as models for the actual plane wave incidence, and the importance of rocket exhaust or plume in determining subsystem response. Near-zone source effects for various incidence angles are analyzed, and coupling through apertures to interior cavities is assessed. For near-grazing incidence angles, source distances greater than 20 ft provide valid simulation for 10-ft models, while for near-broadside incidence, a source distance greater than 40 ft is needed for 10-ft models. Missile plume effects are investigated through use of the thin-wire and body-of-revolution models.
