Book Description
The measurement of the strength of radio frequency fields at high frequency and above has followed practices which are standard for the measurement of field strength at medium and low frequencies. Variability of measurements made in practical situations and a lack of reproducibility of measurements made under apparently identical conditions has prompted an investigation of equipment and methods used in the determinations. The field strength measurement study was undertaken to understand the nature of the problem and to develop techniques for more accurate determinations of field strength and more significant interpretation of measured data. A Stoddart Aircraft Company NM-52A field strength meter which has a frequency range of 375 to 1000 MHz was calibrated and evaluated using conventional methods. Instrumentation to extend the upper frequency limit of the testing procedure from 10 to 20 GHz was procured. Field strength meter antennas in the 2 to 4 GHz frequency range were tested and comparisons made with similar tests conducted by RADC. Methods of simplification of data acquisition and processing for use in aperture synthesis were investigated. (Author).

Book Description
This technical memo represents a simple analytical technique for predicting the Radio Frequency (RF) field inside an enclosed volume in which radio frequency occurs. The technique was developed to predict the RF field strength within a launch vehicle fairing in which some payloads desire to launch with their telemetry transmitter radiating. This technique considers both the launch vehicle and the payload aspects. Hallett, Michael P. and Reddell, Jerry P. Goddard Space Flight Center...
