射电望远镜跟踪系统的研究

Research on Radio Telescope Tracking System

大型射电望远镜在选址、安装和校正方面要求比较高,随着天文爱好者越来越多,市场上需求越来越多的是小型的家用射电望远镜。大部分射电望远镜跟踪装置采用伺服电机驱动,然而伺服电机价格昂贵,因此,在实验室射电频谱仪的基础上,为了降低成本,选用价格相对便宜的改进直流电机驱动射电望远镜进行方位和俯仰转动,选用设计简单、运行可靠的MSP430F169单片机实现对射电望远镜的转动控制和数据信息采集。经过实验室大量实验调试,该系统工作稳定,可以达到设计目标。

Large radio telescopes require high requirements in terms of location selection,installation,and calibration.With the increasing number of astronomy enthusiasts,there is an increasing demand for small household radio telescopes in the market.Most radio telescope tracking devices are driven by servo motors,which are expensive.So,based on laboratory radio spectrometers,in order to reduce costs,relatively inexpensive improved DC motors are used to drive the radio telescope for azimuth and pitch rotation,and select the MSP430F169 microcontroller with simple design and reliable operation to achieve rotation control and data information collection of the radio telescope.Experimental results show that the system is stable,we can achieve the purpose of the design.
