Analysis of image striping due to polarization correction artifacts in remotely sensed ocean scenes

摘要

The characterization of the polarization sensitivity of a remote sensing sensor can have a large impact on the data quality of the top-of-atmosphere radiances measured by optical sensors on earth-orbiting satellites. This paper describes an algorithm to improve the polarization characterization of certain elements of an imaging sensor (e.g. detectors, or mirror sides) relative to each other, as well as the application to an ocean color sensor. The key step in the analysis is the separation of the measured radiances into two groups: those that are increased by the polarization correction, and those that are decreased.
