Zusammenfassung:The invention discloses a high-resolution solar radio data processing system and a method for adaptive burst judgment. The system comprises a paraboloid antenna, a high-speed ADC collector, an FPGA and a computer. A paraboloid antenna for receiving a solar radio signal and outputting two antenna signals to a high-speed ADC collector; The high-speed ADC collector converts the signal into high-speeddigital signal and transmits it to FPGA. FPGA intercept and segments that high-speed digital signal, FFT operation is carry out on each segment respectively, and digital polarization synthesis is carried out in frequency domain to obtain circularly polarize left-hand and right-hand solar radio signals, and that power of the solar radio signals is calculate, and the power of the solar radio signals is integrated according to the time resolution, and the solar radio spectrum signals are obtained and uploaded to a computer; The computer performs adaptive burst judgment and processing on the solar radio spectrum signals,
