Abstract

Polarimetry has been shown to aid in target detection by improving target contrast against both background and clutter. Further, Stokes vector sensors can provide surface orientation and material data, and permit extraction of targets obscured by scattering in the observer to object atmospheric column. This report presents a discussion of the construction of, and data from, the BATC imaging Stokes polarimeter. The polarimeter employs electro-optic modulators to acquire full Stokes vector image sets at a cadence sufficient to freeze target and background motion. These images are co-added to produce the polarimetric SNR necessary to fulfill mission requirements. We discuss the relationship of image timing, integration time, and SNR in the context of specific objectives for the polarimetric products. The relative advantages of implementing different electro-optic technologies will be illustrated by test and field image data.
