Method and device for expanding monitoring range of air craft based on ADS-B

Abstract

The invention discloses a method and a device based on ADS-B which can expand the monitoring range of a plane, provides an information processing method which is based on ADS-B information and is used for expanding the dynamic monitoring range of a plane and a device thereof. The method acquires air traffic information of various planes by analyzing ADS-B information and GNSS information received by the plane and timely updates the mark and position information of the plane, calculates and judges the present status of the plane; when any other plane that does not communicate with the plane appears in the monitoring range, the plane enters a forwarding status, at the moment, the plane chooses a time slot from forwarding time slots to forward the ADS-B information of the other plane, so as to achieve the goal of expanding the dynamic monitoring range of the plane. The method and the device of the invention wholly depend on air-borne electronic equipment of the plane and a satellite navigated receiver, is a self-organized and cooperative plane dynamic monitoring proposal, and especially suitable for the aviation crossing ocean or under severe environmental condition.

Description

technical field [0001] The invention relates to an airborne information processing method and device, in particular to an ADS-B-based method and device for expanding the surveillance range of an aircraft, belonging to the field of air traffic control. Background technique [0002] The fundamental purpose of air traffic control is to make the aircraft on the route safe, effective and planned to fly in the airspace, and the controller needs to monitor the flight dynamics of the aircraft in the controlled airspace in real time. [0003] The traditional radar surveillance method adopts the way of inquiry and response to detect the target. In the long run, the radar system itself has many limitations, which limit the improvement of surveillance performance. The straight-line propagation of the radar beam forms a large number of radar blind spots, which cannot cover areas such as oceans and deserts; the radar rotation period limits the improvement of the data update rate, thereby...

Problems solved by technology

[0009] In his paper "The Connectivity of Ad Hoc Network for Advanced Air Traffic Management", Maggie X.Cheng et al. proposed an air traffic management system related to the ad hoc network based on the UAT data link, which can enhance the airborne ADS-B system Surveillance performance, especially can improve the surveillance range of the airborne ADS-B system; but this paper only gives a concept, does not give the specific implementation of this system
