Contrast Media in the Cardiovascular System,cillation is selected. Then, based on the interference phase of each satellite obtained by nonlinear least squares fitting, a cross-correlation satellite selection method (CCSSM) is established. The available satellites are selected by setting a reasonable threshold. Finally, three multi-satellite c
