<p>PURPOSE:To execute beam tracking of an airplane by an operation mode only for tracking and to improve a search performance of PAR by inputting a height information on an airplane obtained separately even when there is no height information thereon from a transponder. CONSTITUTION:When position data from ASR are inputted to a coordinate conversion element 2, the coordinate conversion element 2 compares the data from the ASR with installation position data on the place of installation of PAR for correction and converts the data from the ASR into position data wherein the PAR is taken as the origin. Receiving the position data as an input, an integrating element 4 integrates them with height information data (height H) from a height information input element 6 and delivers the integrated data to a data converter element 8. A tracking processing element 10 determines a beam number showing an antenna beam, which is sent from the data converter element 8, and outputs it to a beam control element 14. The beam control element 14 starts tracking in the direction of a target corresponding to the beam number from the tracking processing element 10. A radio wave for tracking is displayed in a display element 12 through the tracking processing element.</p> |
