Design of electronic equipment for radio-interference reduction

摘要

During a survey recently conducted for the U. S. Army, Navy, and Air Force, it was found that the control of radio interference was a serious problem to both designers of electronic equipment and to the military operational activities. Some of the critical areas of design that have affected equipment and system performance in the field are discussed herein. Several types of electronic equipment for ground and air-borne applications are discussed including radar, communications, and navigation apparatus. The effectiveness of practical suppression techniques such as shielding and filtering is also considered. Requirements of the current interference specifications are reviewed and techniques discussed for making conducted and radiated measurements of continuous-wave and broad-band interference sources.
