Abstract

The patent discloses an antenna alignment method used for communication scattering in motion and mainly relates to an antenna alignment tracking method on the occasion of scattering equal spot beam communication movement. Alignment process such as link establishing and tracking and the like of scatter communication under the environment of communication in motion can be completed by adding small-size antenna with wide beams based on an original scatter communication device through automatic operation of a control unit without other communication means. The antenna alignment method used for communication scattering in motion has the advantages that other communication means are not needed, the method is accurate and high-efficient, fine in economy, convenient to operate and the like. The antenna alignment method used for communication scattering in motion is especially applicable to real-time alignment of scatter communication antennas under the environment of vehicle-bone and ship-bone communication in motion, and provides support for mechanically establishing a scattering link.

Description

technical field [0001] The invention relates to an alignment method for a scattering antenna in motion in the field of communication, and is particularly suitable for the automatic alignment of the antenna of a scattering communication station at both ends under the condition of low-speed movement, and the rapid opening of a scattering communication system. Background technique [0002] At present, the alignment methods commonly used in scatter communication systems are manual alignment and automatic alignment. Due to the Rayleigh fading characteristics of scatter channels, the signal reception is weak when the communication distance is long; at the same time, it is limited by the antenna beam angle. Due to the characteristics of narrow antenna alignment and insufficient real-time performance of antenna alignment, scattering communication relying on the traditional antenna alignment mechanism can only be used in application environments such as "quiet communication" and "stop...
