11 December 1984 A Ruggedized MMW Radiometer Sensor For Surveillance Applications
Author Affiliations +
A small millimeter wave (MMW) radiometer sensor has been developed that is adaptable to a wide variety of applications including low-altitude remote sensing for passive surveillance and target detection, navigation aid for aircraft, remote sensing from space platforms and precision terminal guidance and munitions. The radiometer is an environmentally hardened, 35 GHz total-power, periodically calibrated receiver with a measurement range of 0 to 500K and a sensitivity of less than 2K for an output bandwidth of 300 Hz. The basic unit without power supply and antenna has a volume of 20 cubic inches, weighs 1.6 lbs, and requires 7 watts dc power. This paper presents a brief overview of the fundamentals of microwave and MMW radiometry and a description of the advanced sensor, including laboratory test results on several units. Examples of airborne radiometric images are described.
