A machine-to-ground wireless communication device and method based on ads-b signal

Abstract

The invention discloses a machine-ground wireless communication device and method based on ADS-B signals, belonging to the field of wireless communication. The device includes a receiving and decoding module, a control module and an antenna module; the control module is connected to the receiving and decoding module and the antenna module; the receiving and decoding module is used to receive the ADS-B signal sent by the aircraft, and decode and obtain readable information and send it to the control module; The module generates control information to control multiple antenna arrays of the antenna module and the corresponding antennas in the antenna array; the frequency shift calculation unit calculates the frequency shift generated by the Doppler effect according to the position, flight speed, flight height and the emission wavelength of the antenna of the aircraft; The compensation unit timely compensates the frequency of the signal transmitted by the antenna according to the frequency movement; the present invention changes the original signal coverage form of the parallel transmission of the antenna to the signal coverage of the air transmission from bottom to top; under the same signal coverage, The antenna sector is smaller, which reduces the radiated energy of the antenna.

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...
