Upgrade of Harry Diamond Laboratories Scale Model Facility. 2. A biconical/Dipole Antenna for Scale Modeling with a Self-Contained Repetitive Pulse Source

Abstract

Harry Diamond Laboratories (HDL) conducts electromagnetic scale model experiments and tests to aid in the prediction of the responses of the external receptors of various Army systems to a simulated field which is representative, in scale, of that which results from a high-altitude nuclear explosion. This high-altitude electromagnetic pulse (HEMP) field simulation may be created by radiating a pulsed field from a biconical/dipole antenna. The resulting field induces currents on the receptors of the model under test, which are sensed and coupled to recording equipment housed in a shielded enclosure. The upgrade for these efforts includes a biconical/dipole antenna that is completely self- contained. That is, the antenna acts as the housing for a pulse source which consists of batteries, a high-voltage power supply, a high-voltage charge, delay lines, a shaping network, trigger circuitry, and a coaxially mounted mercury reed switch (MRS). The antenna is operated remotely through a fiber-optic control system. (rht)
