<P>PROBLEM TO BE SOLVED: To continue tracking while suppressing power consumption when performing change operation of an azimuth of an antenna aperture. <P>SOLUTION: When an aerial wire part 1-3 is driven to change the azimuth of the antenna aperture, a range from an end of a beam scanning range of an aerial wire part 1-2 up to an end of a beam scanning range of the aerial wire part 1-3 becomes a non-scanning range. During the driving of the aerial driving part 1-3, the non-scanning range which is generated due to the driving of the aerial driving part 1-3 is covered, and respective beam scanning ranges of the aerial driving parts 1-2, 1-3 are successively changed so that the beam scanning ranges of the aerial driving parts 1-2, 1-3 are not overlapped. <P>COPYRIGHT: (C)2012,JPO&INPIT |
