<p><P>PROBLEM TO BE SOLVED: To provide an antenna device which can prevent scaleup of shape by employing a reflection mirror type antenna more inexpensive than a phased-array type and shortening a data rate. <P>SOLUTION: The antenna device is provided with reflection mirrors 11, 12 having a bent reflection surface provided on a mechanical rotary driving mechanism 14 and a plurality of linear focal points (lines); and primary radiators 13 each arranged on the plurality of focal points (lines) of the reflection mirrors on the rotary driving mechanism 14, and consisting of a plurality of array antennas capable of electronically scanning the beams in an elevation angle direction using a TRM 15. Multiple beams having different azimuths are formed. This antenna device is applicable as a long-distance search radar. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
