ABSTRACT:
A phased-array radar capable of electronically directing a directional beam of an antenna in any of N different directions, i.e., direction .theta..sub.1 to direction .theta..sub.N. Scanning of the directional beam is effected in any of a long-range mode for detecting and tracking a target cruising at a long range from the radar and a short-range mode detecting and tracking a target cruising at a short range. This reduces the data rate and thereby increases the target information updating frequency associated with a short-range target.
