The Correlation Radar for Combat Surveillance.

Abstract : An exploratory research model of a lightweight, low power consuming, man-portable radar system was developed, capable of detecting, locating and presenting fixed and/or moving targets of interest in a battlefield environment. The CW radar transmission utilizes three modulations: a pseudo-random phase-reversal modulation to obtain range resolution by correlation of the received single with a replica of the transmitted code; a low deviation sinewave frequency modulation for effectively cancelling the inverse 4th power variation of returned signal with range; and a large deviation sinewave frequency modulation for fixed target presentation. For rapid search of an assigned sector, multiple range channels and adjustable automatic scanning are provided. Fixed and moving targets are displayed by A-scope, B-scope and earphones. (Author)
