Abstract : QUENCIES IS M-TO-NOISE RATIO, Sensitivity, Extremely high frequency, Target recognition, Traveling wave tubes, Antennas, Microwave equipment, Detectors. The basic th ory is discussed of a microwave radiometer for ground detection and surveillance. The result is given in e form of a range equation as a function of target and background characteristics, receiver performance, antenna size and scanning rate. A comparison of two types of radiometric systems at various frequencies is made from the standpoints of receiver sensitivity and a figure of merit. Based on he study, a program to develop a submillimeter radiometer is recommended with the objective of eventually achieving a tactical, passive sensing device. (Author)
