Abstract Polarization calibration is an important prerequisite for practical application such as target detection, classification recognition and quantitative inversion. The attitude variance of carrier platform can cause variance of polarization orientation angle, thus reducing the polarization calibration precision. Improved algorithms based on Whitt algorithm is proposed for this problem. In this paper, the problem of these improved algorithms is analyzed in detail, and on this basis, a polarimatric calibration algorithm, which takes channel unbalance into consider and compensates the time-varying attitude pulse by pulse, is proposed, and it can effectively suppress the influence of attitude change on polarization calibration. Simulation results and experimental data processing verify the effectiveness of the proposed algorithm.
