A Fast Alignment Method of Pitch Angle of Scattering System Based on Comprehensive Climate and Meteorological Factors

Abstract

The invention discloses a scattering system pitch angle rapid alignment method synthesized with climate and meteorological factors in the communication field. The method specifically comprises the following stages: a first stage, mainly completing data acquisition under different climate and meteorological conditions; a second stage, analyzing data acquired in the first stage by utilizing relatedknowledge in statistics, and organizing to form a database; and a third stage, applying the database generated in the second stage to a pitch angle alignment process when a scattering system is started, by utilizing previous experiments and data analysis, determining a relation between all kinds of climate and meteorological factors and scatter propagation performances of public bodies, and applying a test result to the pitch angle alignment process of the scattering system, so that time that the system is started is shortened, communication capability of the scattering system in a complex climate and meteorological environment is improved, and an important basis and a feasible method are provided for starting the scattering system under certain special climate or meteorological conditions.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method for quickly aligning pitch angles of a scattering system that integrates climate and meteorological factors. Background technique [0002] At present, the pitch angle alignment of the scattering system only considers the height of obstacles on the communication path and the positional relationship between obstacles and the transceiver system, that is, calculates the initial pitch angle of the antenna according to the longitude and latitude of both the receiver and the transmitter, and searches and corrects the angle error within a certain range After that, the formal communication will begin. However, the antenna pointing calculated only based on the geographical location is not necessarily the best public body position, because wind, cloud, rain, thunder, electricity, fog and other weather all occur in the troposphere, which will affect the performance of scatter...
