High-Performance Reconfigurable Computing (HPRC) is a novel approach to providing the kind of large-scale computing power demanded by modern scientific applications. One of these applications is Backprojection, an image formation algorithm that can be used as part of a Synthetic Aperture Radar (SAR) processing system. Backprojection is an embarassingly parallel application that is ideal for implementation in hardware, especially on reconfigurable computing devices such as FPGAs. This thesis presents an implementation of backprojection for SAR on an HPRC system. It is intended for use in the Swathbuckler project, a joint collaboration of multiple national military research agencies. Using simulated data taken at a variety of ranges, our HPRC implementation of backprojection runs over 200 times faster than a similar software-only program, with an overall application speedup of better than 50x. In addition to excellent single-node performance, the application is easily parallelizable, achieving near-linear speedup when run on multiple nodes of a clustered HPRC system.
