Abstract

The Digital Imaging and Remote Sensing Image Generation (DIRSIG) model is a physics based image and data generation tool developed at the Rochester Institute of Technology. While DIRSIG5 includes a plug-in based architecture and a path-tracing approach to determine the aperture reaching radiance, it does not support polarized radiometric propagation at this time. DIRSIG4 does include this polarized radiometric propagation via Stokes vectors, Mueller matrices, and parameterized polarized bi-directional reflectance distribution functions (pBRDFs). This paper includes an overview of the pBRDF models available to the user, sources of polarimetric reflectance data, and how DIRSIG4 generates a Stokes vector radiance output image. Example imagery of custom targets and full scale scenes will be included to aid users in setting up their own simulations for testing algorithms that require polarized imagery.
