Abstract : This report describes the results of the flight test of the Model 302-A Radiometric System. The appendices are comprised of basic concepts, significant equations and various support data which are germane to this report. The primary objective of the program was to demonstrate that a millimeter radiometric system can operate successfully in a flight environment. The flight tested radiometer was a contrast type, centered at 35 GHz. The platform used for the overflights was a helicopter, flying at speeds up to approximately 90 mph and at altitudes ranging from 100 feet to 700 feet above the targets. Radiometer measurements were correlated in real time with a boresighted TV camera. The corresponding data from the two sensors was transmitted to the ground via a TV link. Targets consisting of light aircraft, trucks and jeeps were overflown. The results revealed that these targets were consistently detected. Some problems were encountered with false alarms due to the random nature of the background. The factor confirms the need for additional development in background discrimination techniques. (Author)
