MILLIMETER RADIOMETER MEASUREMENT PROGRAM,
Abstract
A measurement program was conducted to obtain, through the use of a passive detection system, basic data on the thermal contrasts from tactical military targets at 4.3 millimeters. A laboratory-designed and -constructed switched-type 4-millimeter radiometer enabled continuous comparison between the target or antenna temperature and that of a selected reference. The radiometer was calibrated to indicate temperatures hotter or colder than that of the chosen reference. Measurements were made at three beamwidths: 1 degree pencil beam, 12.5 degrees x 15 degrees, and 7 degrees x 8.6 degrees. With the information derived from this measurement program, it is now possible to design an airborne radiometer operating at 4.3 millimeters. (Author)
