Claim Text:
1. A method for polarimetric calibration of a remote sensor, comprising: receiving at a processor image data collected at the remote sensor representing radiation of at least one of a neutral source and a polarized source reflected from a plurality of reflective mirrors, wherein reflected radiation from each of the plurality of mirrors is plane or circularly polarized with a known set of polarization metrics, each of the plurality of mirrors having a radius of curvature and s and p reflectance, the radius of curvature providing control of an s and p polarization intensity of the reflected radiation; and determining by the processor, one or more polarimetric calibration metrics for the remote sensor based on a known at-sensor s and p radiation intensity for each of the plurality of reflective mirrors and the one or more known polarization metrics of the reflected radiation for the respective reflective mirror.
