Abstract

An airport passive monitoring system provided by the invention is used for performing positioning monitoring on an airplane that uses the airport, and is characterized by including: at least four signal receiving processing stations used for receiving mixed pulse signals and judging a pulse front edge to obtain front edge arrival time; and a monitoring central station which performs positioning of the airplane according to the positions of the four signal receiving processing stations and the corresponding arrival time of each front edge, and includes a setting unit which sets any one of the four signal receiving processing stations as a primary station and the other three as secondary stations, a positioning unit which, based on a difference value of front edge arrival time of each secondary station and the primary station, calculates a rough position of the airplane according to a predetermined coordinate system and predetermined positioning rules, a calculation unit which calculates a first distance, a second distance and an included angle based on the rough position of the airplane, and a judgment control unit which judges an exact position of the airplane according to the first distance, the second distance, the included angle and the rough position.

Description

technical field [0001] The invention relates to an airport passive monitoring system and an air traffic management system including the airport passive monitoring system. Background technique [0002] In order to ensure the safe scheduling of aircraft on the airport (for example, aircraft storage, etc.), it is necessary to accurately locate the aircraft that is about to be stored. At present, the airport passive surveillance system is commonly used. [0003] Existing airport passive surveillance systems generally use primary and secondary radars to monitor aircraft positioning. However, these two positioning and monitoring systems have problems such as low measurement accuracy, low data update rate, difficulty in covering the entire regional airspace, and less information. [0004] Based on the above problems, a multi-base station passive time-difference positioning system has emerged. The principle is: the passive multipoint positioning monitoring system adopts a long ba...
