How to focus ASAR raw data of the ENVISAT satellite with a low computacional cost tool



Raw data, Focalization, Omega-k, ASAR, ESA, ENVISAT


This document details how to use the ASAR sensor parameters of the ENVISAT satellite to focus the raw data from the level 0 files using the Omega--K algorithm. In addition, it serves as an alternative to focus through an Open Source tool with a low computational cost. As a preliminary result, pseudo-images of two regions of Venezuela were processed with the developed algorithm and a qualitative comparison with pseudo-images of level 1 of the same regions provided by the European Space Agency is discussed.
