Two groups of spikes were recorded by the 1.08 ～ 2.04GHz spectrometer of National Astronomical observatories of China on 27 October 2003.The mean and minimum bandwidths of spikes are calculated with two different methods based on the wavelet analysis.The first method determines the dominant spike bandwidth scale based on their scalegram, and the second method is a feature detection algorithm in the time-frequency plane. Finally the results are compared and discussed.
Key words： solar microwave bursts; spike; wavelet transform
