Abstract :
WIDE-FIELD radiometer Model R-4K1 is designed for making radiometric measurements of fast-moving targets. It can be used under conditions where mechanical mounting and pointing systems are too slow or too inconvenient for use in acquiring and tracking such targets. The instrument weighs 13 pounds and is constructed to be held and pointed much as a shotgun, for ease of handling and rapid acquisition and tracking of the target. Because of these and additional features the Model R-4K1 is ideally suited for field measurements of the radiation from high-speed missiles and aircraft.
