The output result images of simulation data. a The output of sparse component obtained by the IALM algorithm on original simulated RF data. It is a typical good result representing correct decomposition and pure sparse components. b The output of sparse component obtained by the ADM algorithm on original simulated RF data. It is a typical noisy result with background noise as sparse components. c The output of sparse component obtained by the OSTD algorithm on processed simulated RF data with larger dynamic range. The algorithms with a CNR less than 1 in Table 3 give such results with pure background because they only show the sparsest parts
