Antenna array single-t / r scaling method based on timing control and medium

Abstract

The application belongs to the field of spaceborne microwave radars, and discloses an antenna array surface single T / R calibration method based on timing control and a medium. A scheduling module sends a control parameter package to a monitoring timing module, the monitoring timing module sends a timing signal and a wave control instruction to a wave control subsystem, when the wave control subsystem receives a rising edge of a frame synchronization signal in the timing signal, the wave control subsystem initiates single T / R calibration of a current frame, and then switches different T / R components according to a beam setting pulse in the timing signal, and cooperates with an internal calibrator until single T / R calibration of all T / R channels of the antenna array surface is completed. Through the in-frame timing switching control of the T / R components by the operation distribution module in the wave control subsystem, compared with the switching mode of sending a control instruction by the scheduling module, the efficiency of single T / R calibration of a large-scale antenna array surface is improved, and the time required for T / R channel calibration of the whole array surface is shortened.
