Response Of Typical Aircraft Antennae To Fast Risetime EMP

Abstract

The response of 15 aircraft antennae to fast risetime EIW (FREMP) was determined by experimentally measuring their response to a surface electric field in the frequency domain, transforming the response into the time domain and convolving the result with the Bell Laboratories double exponential and a full amplitude step function. The step response could be 3 to 5 times as high as the double exponential response. Analysis of the measured antenna responses with respect to their physical dimensions showed that a reasonably good estimate of the antenna's transfer function could be obtained from its overall physical dimensions.
