SATELLITE TRANSMITTING ANTENNA BEAM PATTERN IN LOW ORBIT SATELLITE COMMUNICATION SYSTEM AND CALL CONNECTION METHOD

摘要

Purpose a: artificial satellite of intensity that the satellite transmission antenna beam pattern in a Low-Orbit Satellite Communication system and its call access method is arranged to compare the intensity of multiple pilot signals received from multiple artificial satellites and selection has a great improvement over the previous arrangement. Construction: a duplexer (31) receives a signal and separates a satellite transmission signal from receiving in signal. Satellite transmission signal is divided into aspect direction. by one power divider (32)The n antennas of the equipment (33) of direction phase transitions are connected to n directional aerials input terminal and control a phase of satellite transmission signal. One cell orientation antenna input signal is divided into each antenna in direction by one direction power divider (41). The equipment (42) of one direction phase transitions is connected to a phase of directional aerial input terminal and control unit directional aerial input signal.
