Solar Radio Wide‐Band Spectroscopy and Imaging Facilities of the Chinese Meridian Project Phase II by Yihua Yan et al.

February 3, 2026

Radioheliographs and wideband solar radio spectrographs are essential components of the Chinese Meridian Project (CMP)‐II (C. Wang et al., 2024) that aims to monitor the whole solar‐terrestrial chain of space weather events, from the lower solar atmosphere to near‐Earth space. This work introduce the CMP‐II radio instruments, including the MUSER‐L/I/H, the super‐wideband spectrographs of Mingantu and Chashan stations covering the wideband range of 30 MHz–15 GHz. The overall design, some […]

The physics of solar spectral imaging observations in dm-cm wavelengths and space weather by Tan et al.

January 17, 2024

Recent years, several new generation solar radio telescopes operating in the centimeter decimeter (dm-cm) wavelengths have emerged in the world, including the Mingantu Spectral Radioheliograph (MUSER, 0.4-15GHz) (Yan et al. 2021), the Expanded Owens Valley Solar Array (EOVSA, 1-18GHz) (Gary et al. 2018), and the Siberian Radio Heliograph (SRH, 3-24GHz) (Altyntsev et al. 2020). Due to the fact that the solar radio emission in dm-cm wavelengths mainly originates from the […]

Scaling-laws of Radio Spike Bursts and Their Constraints on New Solar Radio Telescopes by Baolin Tan et al.

June 18, 2019

Radio observation is one of the most important methods in solar physics and space science. Sometimes, it is almost the sole approach to observing physical processes such as the acceleration, emission, and propagation of non-thermal energetic particles, etc. Long-term observation and study have revealed that a strong solar radio burst is always composed of many small bursts with different time-scales. Among them, a radio spike burst is the smallest one, […]
