Sarcomp - A High-Performance Library for SAR Processing

Abstract:
Synthetic Aperture Radar (SAR) captures vast amounts of raw data from satellites and specialized aircraft, necessitating advanced processing for image synthesis. This paper delves into optimization techniques for SAR processing, spotlighting the Fast Fourier Transforms (FFT) and Sinc interpolations. The primary goal is enhancing SAR processing efficiency. We introduce Sarcomp, a SAR processing library in C with a Python API, leveraging SIMD, OpenMP, and cache optimizations. Compatible across x86 (Intel and AMD) and ARM architectures, Sarcomp offers a platform for accelerating SAR processing workflows. Based on tests across multiple architectures, our results validate the effectiveness of the proposed methods.
