STUDY OF THERMAL MICROWAVE AND RADAR RECONNAISSANCE PROBLEMS AND APPLICATIONS

Abstract

Theoretical and experimental studies of the apparent temperature of an isolated object in a thermal background are discussed. Theoretical studies show that the 2 components of apparent temperature of such an object (emission and scattering) can both be calculated from the complete bistatic scattering pattern of the body. Experimentally, 2 radiometers, at 3 cm and 4 mm were constructed, and the former was used to measure the apparent temperature of a controlled target under several conditions. The feasibility of radiometers for surveillance is discussed, including the effects of target velocity and fluctuations in background temperature. (Author)
