Embodiment Construction

[0014] Below in conjunction with specific embodiment, further illustrate the present invention, it should be understood that following specific embodiment is only for illustrating the present invention and is not intended to limit the scope of the present invention, after reading the present invention, those skilled in the art will understand various aspects of the present invention All modifications of the valence form fall within the scope defined by the appended claims of the present application.

[0015] The present invention is mainly based on the limitations of the existing radar performance (the update period of the air traffic control radar is 4 seconds, and the update period of the MDS DC servo driver is 1 second), how to obtain each radar in real time and accurately between two periods The precise position of the incoming flight has become the key to this invention; the update and algorithm of the monitoring data of this invention have been well solved.

Abstract

The invention provides a method for monitoring an aircraft in an airport terminal area, which comprises the following steps of: transforming the longitude and latitude of a horizontal position of a target aircraft into coordinates of a monitoring coordinate plane by using spherical azimuthal projection, judging whether the aircraft tends to fly towards noninvasive area, and if the aircraft tends to fly towards the noninvasive area, giving an alarm. By the method, the calculation accuracy is improved, the positioning accuracy of a descended airplane is improved, the capacity of closely spaced parallel runways forming pentagon in continuously approaching aircrafts is increased, a reliable judgment basis is provided for controllers to timely know parallel approaching positions, the load of the controllers is greatly reduced, and errors, omissions and forgetting of the controllers are effectively avoided.

Description

technical field [0001] The invention relates to an aircraft monitoring method, in particular to an aircraft monitoring method in an airport terminal area. Background technique [0002] The short-distance runway comes from the English word closely spaced parallel runway, which is a combination of parallel runway related operations. Referring to the regulations of the FAA and some European countries, a close runway is defined as the distance between the centerlines of two parallel runways less than 760 meters, one of which is used for takeoff and the other for landing. To establish a relevant safety separation between takeoff and landing, this requires the use of parallel approach non-intrusion area monitoring technology. [0003] A large and medium-sized international airport has about 1,000 daily flights, and one runway can no longer meet the requirements, which will affect the punctuality of flights and the operating efficiency of the entire airport. The short-distance ru...
