Measurement of RF Pick Up. Improved Equipment for Assessment of RF Hazard in Firing Circuits of Weapons Containing Wire-Bridge Electrically Initiated Explosive Devices (EIED)
Abstract
The EMI Hazard Measuring Equipment for use on rf trials, described in R.A.R.D.E. Memorandum 29/69, has been improved and the Mk.2 equipment is described. The new equipment monitors the rf hazard using a thermistor attached to the bridge-wire. The thermistor forms the active arm of a dc bridge and the output of this bridge gives frequency modulation of a pulse generator contained within the weapon under test. These pulses are conveyed to a remote indicator by a magnetic and acoustic link where they are integrated and displayed as a dc signal on the hazard meter. A remote 'zeroing' facility is provided at the indicator unit allowing the bridge to be balanced under conditions of zero hazard.
