Synthetic aperture radar signal processing in parallel using GPGPU

In this work an efficient parallel implementation of the Chirp Scaling Algorithm for Synthetic Aperture Radar processing is presented. The architecture selected for the implementation is the general purpose graphic processing unit, as it is well suited for scientific applications and real-time implementation of algorithms. The analysis of a first implementation led to several improvements which resulted in an important speed-up. Details of the issues found are explained, and the performance improvement of their correction explicitly shown.Instituto de Investigación en InformáticaComisión de Investigaciones Científicas de la provincia de Buenos Aire
