With the development of solar radio spectrometer, it is difficult to process a large number of observed data quickly by manual detection method. An automatic detection method of solar radio burst based on Otsu binarization is proposed in this paper. In this method, channel normalization is used to denoise the original solar radio image. Through experimental comparison, Otsu method is selected as a binary method of solar radio spectrum, and Open and Close operations are used to smooth the binary image. Experiments show that the proposed method for automatic detection of solar radio bursts is effective
