<p>PURPOSE:To enhance safety by making the control of an airfield efficient by converting the target video data from both of a radar apparatus for monitoring the peripheral air area of an airport and an airport surface detection radar apparatus to digital data to use the same. CONSTITUTION:A tracking apparatus 3 converts the position data from a target detector 2 obtained at each time when an antenna is rotated to flight path data 10 and supplies the data 10 not only to a radar display apparatus 5 for a terminal but also to a tracking apparatus 8. An airport surface detection radar 6 detects the response from the airplane or vehicle running on a runway or a guide path as a radar video signal to convert the signal to the position data of a target by a target detector 7. The apparatus 8 takes the correlation due to the data 10 and a position and speed to discriminate the targets present within a definite range as the same target and applies a call sign to target data with respect to one to which flight plan data is applied by the apparatus 3 to send the data to a radar display apparatus 9 for a tower and applies a position symbol and a call sign mark to the target to display the target.</p> |
