| Abstract: | Factors which affect the pointing error of antenna beam are analyzed in directional communication system.
The relation between the pointing error of antenna beam and attitude angles is given for a special situation, meanwhile,
a deduction method to obtain the relation between the pointing error of antenna beam and attitude angles based on least
square estimation for a general situation is given. The relation and the method presented provide theoretical basis to analyze
the pointing error of antenna beam for directional communication system, the results are good for estimating the
situation of beam aim for directional communication system. |
