Quick and automatic alignment method for static satellite communication narrow beam antenna

Abstract

The invention discloses a quick and automatic alignment method for a static satellite communication narrow beam antenna, and relates to the field of the communication technology. The alignment methodcomprises the following steps that: 1) both communication parties finish the coarse alignment of an antenna through link planning; 2) a receiving end antenna azimuthal angle is subjected to refined alignment; 3) a transmitting end antenna azimuthal angle is subjected to refined alignment; 4) a receiving end antenna angle of pitch is subjected to refined alignment; and 5) a transmitting end antennaangle of pitch is subjected to refined alignment. In order to solve the problems that antenna alignment time is long and an antenna direction deviates from an optimal scattering region in a scattering communication system starting process, the method utilizes the characteristics of a practical channel and combines with an antenna directional diagram to carry out the automatic alignment of the antenna through data analysis and a related algorithm, system starting time is greatly shortened, antenna alignment can be quickly finished without being affected by fading channels, disturbance bodies or interference signals, and the method can be applied to antenna alignment in a scattering communication system and other systems.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a fast automatic alignment method for a narrow-beam antenna in static mode. Background technique [0002] The fast turn-on of the diffuse communication system and other narrow beam antenna systems is mainly determined by the alignment time of the antenna. Since the beam of the antenna is narrow and the communication distance is long, to ensure the quality of communication, the antenna must be pointed to the best scattering area. [0003] At present, there are two methods for antenna alignment in scatter communication systems, that is, manual alignment with the help of instruments and automatic alignment based on software, but no matter which method is based on two-dimensional scanning of azimuth and elevation, after the two-dimensional scanning is completed The antenna attitude angle corresponding to the maximum signal point is the precise alignment angle of the antenna. ...
