Spectrogram and time-domain statistical analysis plots of the CSO Meter-wave Solar Radio Observatory System and the surrounding environmental interference. Panel (a) shows the dynamic spectrum, and panels (b)–(d) show the ADC time-domain sampling results. Panels (e) and (g) show the data obtained by the CSO Meter-wave Solar Radio Observatory System, while panels (f) and (h) show the corresponding environmental noise detected by the test antenna.
