Due to the complexity of electromagnetic environment and the limitation of radar receivers, radar signals sorting in underdetermined case is a challenging task. After analyzing the applicability of the sparse component analysis (SCA) and the sparsity of intra-pulse modulation radar signals, an underdetermined blind sorting method based on the SCA for radar signals in time domain is presented in this paper. The experiments by intra-pulse modulation radar signals show that, compared to uselessness of traditional sorting methods, the algorithm is valid in some tough case.
