Field Compensating Scattering Structures in ARES for Dispersed EMP testing of Satellites
Abstract
Measurements up to 130 MHz in the ARES show non-uniform field variations of 10 dB. 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 eliminated the field non-uniformity caused by signal reflections at equivalent frequencies higher than 30 MHz. current measurement on models of the structures of the fleet communications satellite in the ARES model indicates 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.
