Machine-ground wireless communication apparatus and method based on ADS-B signal

Abstract

The invention discloses a machine-ground wireless communication apparatus and method based on an ADS-B signal, and belongs to the field of wireless communication. The apparatus comprises a receiving and decoding module, a control module and an antenna module; the control module is connected with the receiving and decoding module and the antenna module at the same time; the receiving and decoding module is used for receiving the ADS-B signal sent by an aircraft, decoding the ADS-B signal to obtain readable information, and sending the readable information to the control module; the control module generates control information to control a plurality of antenna arrays of the antenna module and corresponding antennas in the antenna arrays; a frequency shift calculation unit calculates the frequency shift of generated by a Doppler effect according to the position, the flight speed and the flight height of the aircraft and the transmitting wavelength of the antennas; and a frequency shift compensation unit performs proper compensation on the frequency of the transmitting signals of the antennas according to the frequency shift. By adoption of the machine-ground wireless communication apparatus and method, the original parallel transmitting signal coverage mode of the antennas is changed into the signal coverage of transmitting to the air from bottom to top; and under the same signal coverage, the sectors of the antennas are smaller, and thus the transmitting energy of the antennas is reduced.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to an ADS-B signal-based machine-to-ground wireless communication device and method. Background technique [0002] ADS-B (Automatic Dependent Surveillance-Broadcast) is a broadcast automatic dependent surveillance system, which relies on accurate global satellite navigation and positioning, operates around the clock, monitors (acquires) information such as the position, altitude, speed, heading and identification number of the aircraft, and realizes Between, and between the aircraft and the ground station broadcast their respective information data. Without manual operation or inquiry, parameters can be automatically obtained from relevant airborne equipment to broadcast aircraft information to other aircraft or ground stations for controllers to monitor the status of the aircraft. In view of the various advantages of ADS-B, at present, the construction of ADS-B system is bein...
