<p><P>PROBLEM TO BE SOLVED: To provide a precision approach radar system realizable in a system acquired by simplifying a switching system of an antenna. <P>SOLUTION: Each amplification operation of a transmission part 131 of an azimuth antenna device 13 and a transmission part 141 of a height antenna device 14 is switched on/off alternately at every repetition of beam scanning in a control part 16, and some one of each output from A/D converters 151, 152 is selected to a signal processor 153 in a signal processing part 15, to thereby switch alternately the azimuth antenna device 13 to/from the height antenna device 14. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
