Background radiation correction-based polarization remote sensor short wave infrared band polarization calibration method

The invention discloses a polarization remote sensor short wave infrared band polarization calibration method based on background radiation correction, and the method comprises the steps: constructing a polarization response measurement model and a background radiance model, and measuring a Stokes vector of target radiation; determining a background radiation polarization response mathematical model caused by an internal system of the remote sensor by adopting a sub-band method; acquiring a background radiation measurement matrix by using the light source and the polarization system; establishing a background radiation polarization response mathematical model caused by the internal background radiation by determining a correlation coefficient between the external background radiation and the internal background radiation; according to the actual operation state of the polarization remote sensor, establishing an inversion improvement model based on the polarization degree after background radiation correction;
