Solar activities, including phenomena such as solar flares and coronal mass ejections (CMEs), can generate solar radio bursts. This phenomenon has a significant impact on Earth's radio communications, satellite navigation, and infrastructure. Monitoring and studying them are crucial for space weather forecasting and solar activity research. This paper develops a dual-channel wideband decimeter-wave solar radio spectrometer system using software-defined radio (SDR) technology. The system can perform signal processing on signals in the frequency range from 100 kHz to 6 GHz and can monitor in real time.This spectrometer has the characteristics of SDR openness and modularization, and performs spectrum analysis through mixing, A/D conversion, and FFT. It has the characteristics of wide band, high spectral and time resolution. The monitoring visualization software is used for setting parameters, displaying data, and drawing waterfall diagrams. This system is on the 10-meter radio telescope of Yunnan Observatory and is applied to the observation in the frequency band of 700 - 1500 MHz. After nearly one year of testing, it successfully captured solar radio burst events.This system has high stability and practicality, and provides reliable data support for solar radio research and space weather forecasting.
