Real-time processing of SAR images for linear and non-linear tracks
2016
A distributed real-time processing framework is used to implement a generic processor for linear and non-linear tracks. The focus is on the implementation of direct back-projection (DBP) and fast factorized back-projection (FFBP) algorithms in the framework. The software is described in detail on how it is tailored to achieve a real-time computation of a SAR image using multiprocessors, multicore CPUs and GPUs. Results are validated with airborne SAR data acquired by the DLR's F-SAR sensor.
