This document describes the process of focusing the raw data from level 0 files of the ENVISAT ASAR instrument using the Omega-k algorithm. Here we give some implementation details of the Omega-k algorithm. The aim of this work is the creation of a computational tool in Python for processing ASAR raw data. 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.
