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.
