| 摘要 | The high frequency-very high frequency(HF-VHF) frequency band is of significant importance in astronomical observations, with applications studying various phenomena such as space weather, solar radio emissions,planetary eruptions in the solar system, pulsars, transient sources, and reionization of the early universe. This article introduces the HF-VHF frequency band multifunctional radio astronomical terminal system based on a dual-channel high-speed acquisition board with a frequency observation range of 1-250 MHz and a sampling rate of 500 Msps(Mega samples per second). The maximum quantization bit of the system is 14 bits, with a maximum time resolution of 0.1 s and a maximum spectral resolution of 16 k Hz. The system combines spectral analysis of solar radio signals and recording of time-domain data of signals interfering with long baselines, and adopts a server-client separation mode to allow remote operation with separate permissions. It is used in the China-Malaysia joint astronomy project,which can carry out single-site observation of solar radio signals as well as interferometric observation of signals from multiple sites. |
