Satellite communication array transceiver

摘要

A satellite communications system (10) that employs an array of separate and easily deployable antennas (12) for transmission and reception purposes to accommodate high data rate transmissions. The antennas (12) can be deployed randomly at a communications site and are physically separated. Each antenna (12) transmits and receives the same information. A coded signal is used to identify the transmission from each antenna (12) for calibration purposes to align the bits transmitted by each antenna (12) and provide carrier frequency phase matching. The coded signals are used to compare the phase and timing relationship between each antenna signal and a reference antenna signal when the separate antennas receive all of the coded signals. Correction computations are performed and specialized phase and data alignment systems (24, 32) are employed to delay and adjust the phases of the various transmitted signals relative to the reference antenna (12) to provide the desired alignment. Additionally, phase and timing systems (194) are used to determine and correct the phase and data variations between the data received by the antennas (12) so that they can be combined and processed.
