ELECTRONIC SCANNING RADAR
Radar - 3-D
December 6, 1960
ARTIST'S CONCEPTION illustrates the transformation which has taken place on America's newest missile cruiser and destroyers with the installation of Frescan, electronic scanning radar, which features electronic data stabilization.
This powerful, lightweight, all-weather radar was developed for the U. S. Navy by the Hughes Aircraft Company, Fullerton, Cal.
Upper panels illustrate conventional radar systems, which require combinations of multiple antennas, transmitters, or receivers to provide three-dimensional airborne target information (range, height, bearing).
These also need heavy, mechanical gyro-stabilizing antenna equipment to compensate for pitch and roll of a ship at sea.
Lower panels show slimmed down Hughes radar. Frescan reduces antenna weight on the masthead to less than 2,800-pounds.
Its pencil-shaped, electronically scanned beam detects targets and instantly displays pin-point target information for the missile destruction of enemy aircraft.
Only one antenna, transmitter and receiver are necessary to obtain 3-D information
