| 摘要 | A process for measuring antenna gains of a transmitter for generating at least one radiation pattern of the antenna, the process including a plurality of transmissions of a test signal sent to a satellite to retransmit the test signal to a second terrestrial station, the transmissions being carried out according to different orientations, the test signal being spread spectrum modulated by a pseudo-random numerical sequence; a reception of each test signal; a demodulation of each test signal making it possible to measure the power of each test signal received; a comparison of each power with a first threshold; a generation of an encoding instruction aiming to encode a given number of sequences of data bits by at least one pseudo-random sequence. | ||

| 主权项 | 1. A process for measuring antenna gains of a transmitter of a first terrestrial station for generating at least one mapping of a coverage of said antenna, the process comprising: performing a plurality of transmissions of a test signal, by the transmitter of the first terrestrial station, sent to a satellite, the satellite including a repeater to retransmit the test signal to a second terrestrial station, the transmissions by the transmitter of the first station being carried out according to different orientations of the antenna of the transmitter, said test signal being spread spectrum modulated in a channel of predetermined width by a pseudo-random numerical sequence (PN) encoding at least one sequence of data bits generated by a computer of the transmitter; receiving each test signal by a receiver of the second terrestrial station; demodulating each test signal making it possible to measure a received power of each test signal; comparing each power with a first predefined reference power threshold, and generating an encoding instruction aiming to encode a given number of sequences of data bits by at least one pseudo-random sequence in a same test signal when said received power of a test signal is below the first power threshold. | ||
