Mingantu CSRH Station

The Chinese Spectral RadioHeliograph (CSRH) is a state-of-the-art imaging telescope array, which will operate at centimeter and decimeter wavelengths (0.40 - 15.00 GHz). It has 100 antennas with diameters of 2.0 and 4.5 m in a 3-arm spiral array. It will obtain full imaging observations of the solar chromosphere and corona by using aperturesynthesis technology.


CSRH began construction in 2009 and is located in Inner Mongolia. It represents a new generation of solar radio telescopes that can generate observations with high spatial, temporal and spectral resolution. It will play a key role in solar physics and space weather studies. Results from this project will advance any knowledge of the Sun.
