To cope with the circumstance without considering wideband for the DOA estimation method under SαS noise,on the basis of analyzing the character of wideband array output matrix in SαS noise,the temporal method and the frequency domain method are combined by constructing every frequency band of fraction cumulant of the L-shape array,which could extend 1-dimension wideband signal to 2-dimension.
