<p><P>PROBLEM TO BE SOLVED: To carry out target (aircraft) surveillance with high reliability in a mode S secondary surveillance radar system. <P>SOLUTION: A surveillance processor 39 produces a detection report of acquisition surveillance by a scan of an antenna thereafter by adopting the mode A code information with coinciding code data among mode A code information acquired by scans of a plurality of times. In this way, the efficient utilization of RF channels during the roll-call period can be maintained while improving the reliability of a target detection report. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
