Numerical Analysis of Sunshine Temperature Field in Circular Focal Antenna
In view of the lack of annular focus antenna cases in the existing temperature field studies,the sunshine temperature field of a 12 m antenna during 9:00～16:00 is simulated in this paper.The temperature difference between the antenna components and the hour-by-hour temperature change trend of the main reflector and the back frame are ana-lyzed.The results show that the difference of heat received and thermal property parameters between antenna components will cause large temperature difference between components.The mutual occlusion between antenna structures will result in obvious temperature gradient inside the structure.The temperature difference inside the component is related to the unifor-mity of temperature distribution.
