Study of EMP Testing of Satellites.

Abstract

Measurements up to 130 MHz in the ARES show non-uniform field variations of 10 dB peak-to-peak. Similar measurements of the field within a 1/30 scale model of the ARES show similar results. Three different scattering structures tested in the ARES model reduce the field non-uniformity caused by signal reflections at equivalent frequencies higher than 30 MHz to less than 3 dB peak-to-peak. Current measurements on models of the structures of the fleet communications satellite in the ARES model indicate that a scattering structure is necessary. Resonances that occur below 25 MHz on the wire top plate of the ARES can be tolerated. A potentially inexpensive and effective scattering structure made by stringing wires in the terminating half of the ARES was designed and is recommended for the ARES. (Author)
