Abstract
A calibration method includes: acquiring eight error models obtained after a preliminary calibration of a Terahertz frequency band system; based on the eight error models, determining a first mathematical model according to a first S parameter related to a first calibration piece, the first mathematical model comprising parallel crosstalk terms between probes, and determining a second mathematical model according to a second S parameter related to a second calibration piece, the second mathematical model comprising series crosstalk terms between the probes; determining a third mathematical model according to a third S parameter related to a measured piece; and solving and obtaining a Z parameter of the measured piece based on the first mathematical model, the second mathematical model and the third mathematical model, and acquiring an S parameter of the measured piece according to the Z parameter of the measured piece.
