Synthetic Aperture Radar (SAR) Image Processing Toolbox for Python. Current capabilities include modeling the phase history for a collection of point targets as well as processing phase histories using the polar format, backprojection, and omega-k algorithms. Autofocusing can also be performed using the Phase Gradient Algorithm. The current version can interface with AFRL Gotcha and DIRSIG data as well as a data set provided by Sandia.
