Test and Evaluation of the Air Traffic Control Radar Beacon System Electronic Scan Antenna (Specification Tests).

摘要

The air traffic control radar beacon system (ATCRBS) electronic scan antenna (ESA) consists of 56 array modules placed on a platform (ring) constructed around the top of an airport surveillance radar tower. A shelter beneath the tower provides an enclosure for the control and radiofrequency (RF) distribution system of the ESA. This interim report covers the specification tests to determine compliance with portions of the engineering requirement applicable to field testing. It was concluded that the ESA performed the basic functions of beam stepping, agile beam repositioning, beam hopover and the generation of side-lobe suppression (SLS), improved SLS (ISLS), sum channel, and difference channel antenna beam pattern characteristics. The data obtained during the effort met the specification requirements, taking into account field environmental effects.
