Airport surface traffic control system
First Claim
1. An airport surface traffic control system, comprising:
- an airport surface detection radar for receiving reflected radar signals from targets moving in an airport;
a first target detector for outputting location information of targets by calculating target locations obtained from a signal outputted from the airport surface detection radar;
a first monitoring radar for receiving reflected radar signals from airborne targets in an area around said airport;
a second monitoring radar for receiving response signals including beacon codes from said airborne targets;
a second target detector for outputting location information and beacon code information of targets in response to target location information from the first monitoring radar and signals from the second monitoring radar;
a flight schedule information processor for outputting aircraft flight schedule information;
an ID code addition apparatus for identifying targets and their locations in response to location information outputted from the first and the second target detectors and developing target display data signals corresponding to said targets and their locations, adding ID codes to said display data signals according to the beacon code information and the flight schedule information, and outputting said display data signals; and
a display apparatus for indicating locations of targets moving on the airport surface and symbols and ID codes corresponding to the targets in response to said display data signals from the ID code addition apparatus.

Abstract
An airport surface traffic system is provided which detects targets moving on an airport surface and automatically adds ID codes thereby reduces the controlling duties of an air traffic controller and elevates safety of an aviation control. An airport surface traffic system comprises airport surface monitoring radars which detects targets moving on an airport surface, ASDE target detector which detects targets by an output signal of the airport surface monitoring radars, a second monitoring radar which receives response signals from airplanes and from an airport monitoring radar which controls airport, ASR/SSR target detector which detects targets, ID code addition apparatus which adds an ID code to targets based on a signal from FDP which stores flight schedule data of airplanes and a multi-function display which displays targets.
