Electromagnetic interference environment measurement and prediction considerations
Robert T. Disney
Abstract: The determination of an optimum receiving system for a given class of signals or how satisfactorily a given receiving system will operate requires information on the interference environment in which the system must operate. The important interference parameter s required for estimating expected system performance are power density, amplitude probability distribution functions, time statistics at various amplitudes, and auto-covariances as functions of time, location, frequency, polarization, and direction of arrival, Considerations for the establishment of programs to obtain this information and a discussion of the measurement of the environment are given.
