Method and device for carrying out polarization calibration on lunar orbit synthetic aperture radar

The embodiment of the invention discloses a method and a device for performing polarization calibration on a lunar orbit synthetic aperture radar. The method comprises the following steps: acquiring a first echo signal and a second echo signal; performing matched filtering processing on the first echo signal and the second echo signal to obtain first pulse pressure data and second pulse pressure data after pulse compression; respectively extracting data module value maximum value points from the first pulse pressure data and the second pulse pressure data to obtain first calibration data and second calibration data; calculating a transmitting end error parameter and a receiving end error parameter of the lunar orbit synthetic aperture radar based on the first calibration data and the second calibration data; the transmitting end error parameters comprise amplitude-phase imbalance parameters and crosstalk quantity between a horizontal transmitting channel and a vertical transmitting channel of the lunar orbit
