太阳跟踪及射电辐射测量技术研究

Research on solar tracking and radio radiation measurement

为了实现对太阳自动跟踪以及太阳射电辐射的测量,使用STM32微处理器作为小型射电望远镜的控制核心,利用TCP传输方式解决了RS-485传输中存在的传输速度与传输距离不能兼顾的问题,从而提高了太阳射电望远镜观测数据的时间分辨率。该系统实现了时间分辨率为1 ms的太阳射电数据采集与存储,结合视日轨迹运动跟踪的方法,将自动跟踪精度调高到0.08°。通过对数字滤波算法仿真,在原有滤波算法基础上设计了满足系统的数据处理算法。

In order to realize the automatic tracking of the sun and the measurement of solar radio radiation, the STM32 microprocessor is used as the core of the control of the small radio telescope. The TCP transmission mode is used to solve the problem that the transmission speed and the transmission distance in the RS-485 transmission can not be solved. The time resolution of the solar radio telescope for observing data is further improved,and the system realized 1 ms time resolution of solar radio data acquisition. The automatic tracking precision is up to 0.08 degrees by the method of tracking the trajectory motion of the view day. By simulation of the digital filtering algorithm, the data processing algorithm which satisfies the system is designed on the basis of the original filtering algorithm.
