Abstract: To achieve full-band observation of solar radio emissions, the sun-planetary interstellar monitoring chain subsystem of the Phase II of Chinese Meridian Project will construct four sets of solar radio spectrometers covering the decimeter, meter, decameter, and centimeter wavebands, providing reliable data support for solar physics and space weather research and operations. The system configuration and main technical parameters of the full-band radio spectrometer are introduced, and the data products and calibration process described.
