In this paper, a TDRSS signal simulator is implemented, which can be used to test and compensate the RF channel characteristics of the ground of phased array system. In this paper, the signal characteristic calibration method suitable for the simulator is studied effectively, and its composition and workflow are introduced. The performance of the proposed calibration method meets the requirements of the ground-based beamforming and has been verified.
