基于STM32的射电望远镜跟踪系统设计

Based on the STM32 radio telescope tracking system design

摘要:

为了满足天文爱好者的对射电天文学的探索,对于大型的射电望远镜天线,其指向精度要求高,观测的过程中需要做各种实时修正,造价昂贵,并不适合用于科普,因此设计了一种基于STM32微处理器的双轴射电望远镜控制系统。系统通过两台直流电机控制抛物面天线对太阳的运动轨迹进行跟踪并实时采集射电望远镜接收机电压,并将采集的数据利用TCP传输方式快速送至PC机用户监控软件进行显示和存储。该系统实现了时间分辨率为1ms的太阳射电数据采集与存储,提高了系统捕获持续时间很短的太阳爆发能力,为科普爱好者研究、分析太阳活动提供了数据支撑。

Abstract:

In order to satisfy the astronomer"s exploration of radio astronomy, for a large radio telescope antenna, the pointing accuracy high, needs to be done in the process of all kinds of real-time correction of observation, expensive, is not suitable for popular science, so we design a biaxial radio telescope control system based on STM32 microprocessor. Paraboloid antenna system through two dc motors control for trajectory tracking of the sun and real-time acquisition radio telescope receiver voltage, and data collected by using TCP transport quickly sent to the PC user monitoring software for display and storage. This system has realized the time resolution of 1 ms solar radio data acquisition and storage, improve the system to capture the short duration of the ability of the outbreak of the sun, for the study of the popular science enthusiasts, analysis provides data to support the solar activity.
