The Design, Development and Evaluation of Improved Stc Equipment for Application to ATC Radars

摘要

The need for improved Sensitivity Time Control circuits in Air Traffic Control radar equipment becomes more imperative as Emergency Mission System search and precision radars become more sensitive and all-weather tracking and controlling to within a mile of the radar site becomes standard procedure. This report traces the development of a sophisticated logarithmic STC circuit from previously derived concepts through incorporation in, and evaluation of, the latest EMS search radar. The development of Digital Video Data processing equipment led to design and experimental work on a digital STC concept. The preliminary investigation of this concept indicates that a significant advance in this direction is possible in clutter attenuating devices. Reference is also made to the current EMS system including test results plus recommendations for improvements in anti-clutter devices for present and future search and precision radars. (Author)
