Abstract随着射电望远镜口径的扩大和工作频率的提升,望远镜结构更加复杂,望远镜效率与指向对结构变形也越来越敏感,采用传统的补偿方法已无法满足望远镜电性能的要求,因此有必要对望远镜主反射面进行主动调整来补偿电性能.但是现有的主动面调整技术并不能很好地满足实时性这一重要指标.为此,本文提出一种基于角度传感器的大口径射电望远镜面板面形实时计算方法,利用角度传感器的读数,快速实时地计算出面板的实际位置,为后续面板主动调整量的计算奠定基础,使电性能达到最优.
Other AbstractWith diameter enlarging and frequency upgrading of the radio telescope, the telescope structure is more complex, and the telescope efficiency and steering are more and more sensitive to structural distortion. It is difficult if we adopt traditional compensation method to satisfy the telescope electrical performance requirements, so taking the initiative to adjust the main reflector telescope to compensate telescope performance is essential, but the common active surface adjustment technology does not well meet the important instantaneity index. To this end, this paper proposes a real-time position calculation method for large-diameter radio telescope panel using the angle sensor. The physical position and attitude of the telescope panel can be computed quickly through using the reading of the angle sensors, which can make the active adjustment of the telescope panel more efficient and the telescope electrical performance being better.
