FOCALISATION: A Versatile and Efficient Tool for Raw Data Analysis and RADAR Image Formation

In this paper, we present the FOCALISATION tool developed by SCALIAN for DGA-MI, with the collaboration of the IETR laboratory. The purpose of this tool is to master the image formation process, often overlooked by end-users of RADAR images. This tool implements and enables to apply various focusing treatments, including autofocus, to produce SAR and ISAR images from raw IQ RADAR data. The tool allows for the generation of wide-area images, as well as the specific focusing of a moving target, either cooperative or not. The tool is compatible with various input raw data formats, both from signal simulation tools and real sensors. Moreover, FOCALISATION tool is easily extendable thanks to a plugin architecture for each treatment All these features are available in an all-in-one tool that can be configured through a user-friendly interface and efficient implementation (C++ & GPU).
