Abstract

The extraction of polarization features is the key to the further application of remote sensors. For conventional remote sensing, the evaluation method of polarization characteristics is polarization sensitivity, which needs to be obtained through polarization testing. For polarization remote sensing, it is necessary to obtain the polarization characteristics of the instrument through polarization calibration. Polarization correction requires not only the measurement of the polarization characteristics of the target, but also the calibration of the polarization characteristics of the instrument, and the ultimate goal is to eliminate the polarization response of the instrument. Therefore, it is necessary to carry out research on polarization feature extraction and correction technology. This paper mainly discusses the difficulties and technical approaches of current polarization feature extraction and correction, analyzes the key technologies and related progress, and provides important reference value for further improving the quantitative acquisition of target information.
