C-band network transceiving system based on time division duplex

Abstract

The invention discloses a C-band network transceiving system based on time division duplex, and relates to the technical field of communication. The system comprises an airborne end telemetering and remote control unit, wherein the airborne end telemetering and remote control unit comprises an airborne end C-band broadband network transceiver and an airborne end C-band power amplifier, and has thefunctions of network access, network quitting, parameter setting and state detection; and a ground base station type telemetry and telecontrol unit which is composed of a ground end C-band broadbandnetwork transceiver and a base station type C-band power amplifier, and has data transmission functions of TDD duplex data transmission, state detection and parameter setting. The design scheme of theairborne telemetry and telecontrol unit and the ground base station type telemetry and telecontrol unit solves the problem of air-ground real-time high-speed data transmission. Flight inspection shows that the cross-linking relation between the system and the original aircraft equipment is correct, the normal work of the original aircraft equipment is not influenced, the system function is normal, the performance index meets the design requirement, and a solid foundation is laid for the deepening application of subsequent flight data.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a time-division duplex-based C-band network transceiver system. Background technique [0002] For a long time, in the test flight stage of the test aircraft, the real-time data monitoring method is single, the transmission of information is less, and the real-time performance is poor. There are many inconveniences in timely handling of aircraft failures in the air, flight quality monitoring, and auxiliary flight command. Very uncomfortable. Therefore, by collecting the flight data of the aircraft flight test parameters in real time and downloading them to the ground, the real-time transmission of the aircraft flight data will be realized, which will further expand the application range of the flight data, and then achieve real-time monitoring of important parameter indicators of the test aircraft, and actively respond to emergencies. It is of great significance to ensure t...
