Title: Radar
Inventor: FURUKAWA HIDETOSHI
IPC: H01Q3/26
Filed: 2000-03-23
Abstract: PROBLEM TO BE SOLVED: To provide a radar which can maximize the performance of an antenna irrespective of the position of a target, and improve the tracking accuracy. SOLUTION: An antenna unit 1 having phased array antennas 1-1 to 1-4 is rotated by a drive unit 2 to search for and track the target in a time-sharing manner in the rotational period. The target is tracked based on the azimuth of the target obtained by the search at the time slot around the time point when the differential angle between the azimuth of the target and the maximum gain direction of the antennas 1-1 to 1-4 is minimum. In addition, the gain direction of the antennas 1-1 to 1-4 follows the target over the whole range of the tracking time slot.
