RADIOMETRIC TRACKING OF SMALL ISLANDS.
Abstract
Radiometric measurements have been made at 35 GHz to simulate the tracking of a small island by a satellite-borne system. Both absolute temperature and tracking error measurements were made. The simulation was made using a portable tower to attain altitude and microwave absorbing material on a support in the water off Spesutie Island at Aberdeen Proving Ground as a target. It was concluded that with a 10 sec time constant, conical scan tracking with a 10 in. diameter antenna could achieve pointing accuracies of better than 5 mrad of angle if great care were taken to initially align and calibrate the mechanical, electrical, and spatial axes of the system.
