Abstract : The purpose of this project is to conduct a feasibility study and investigation to determine methods for measuring the interference characteristics (Spectrum signature) of U. S. Army communications equipment deemed necessary for the prediction and minimizing of electromagnetic interference. Investigations to extend the determination of the interference characteristics of U. S. Army communication equipment to include the near-field emission and susceptibility characteristics have been initiated. A literature survey covering (1) anechoic chamber techniques, (2) measurement techniques for evaluating anechoic chambers, (3) absorbing materials, (4) measurement techniques for near-field radiation and susceptibility interference characteristics, and (5) test antenna and near-field probe techniques were conducted. An investigation of stateof-the-art anechoic chamber techniques, chamber evaluation techniques, and absorbing materials was initiated. An investigation to determine the problems associated with near-field measurements, and to develop adequate techniques and procedures for measuring the near-field radiated and susceptibility characteristics of electronic equipments is being conducted.
