Divergence opportunity analysis on zenith-passing blind zone of satellite antenna
摘要
Abstract
The divergence near blind zone state area of satellite antenna with rectangular coordinate frame platform struc-ture and polar coordinate frame platform structure is analyzed. The divergence model of the antenna zenith-passing blind zone was established to calculate the divergence occasion and divergence degree of the rotational angle of the first-stage rotational unit of mechanism antenna blind zone,and their influence on beam taper angle. The single-axis error distribution conditions corre-sponding to different divergence ranges were determined under the conditions of different beam taper angle errors,and the in-fluence of the position and speed error of first-stage rotational unit near the blind zone on space beam error was determined also. The analysis provides a theoretical guidance for the working condition setting of satellite mechanical antenna for the requirement of variable communication links.关键词
