Simulation results of calibration of trapping stiffness and CF with the SDFM, TDFM, and PSDM. The red solid lines with filled circles are the simulation results of the SDFM, and the black dashed lines with filled triangles are the simulation results of the TDFM, and the blue dash dot lines with empty circles are the simulation results of the PSDM. (a) The calibration accuracy of trapping stiffness versus different SNRs. (b) The calibration accuracy of CF versus different SNRs. (c) The calibration accuracy of CF versus different trapping stiffnesses. (d) The calibration accuracy of CF versus different trapping stiffnesses.
