SAR System Engineer

ID de l'offre R0064896 Date de publication 04/10/2019 Lieu: Italie, Italy
Full time, Contrat à Durée Indéterminée (CDI)
Thales people architect and deliver satellite-based systems that help position, connect and observe our planet, and push the boundaries of our understanding of planet's resources. Our systems are in orbit at 400 km, 20000 km, 36000 km and beyond to the edges of the solar system.

Task description:
•    Definition of performance models for SAR Instruments relying on the most advanced architectural features (e.g. deramp-on-receive, SCORE, DBF, FM-CW, etc.) and operating in various space acquisition geometries (i.e. side-looking, squinted-looking, forward-looking). These performance models shall be defined and developed with reference to both standard (i.e. Stripmap, ScanSAR, Spotlight) and advanced SAR acquisition techniques (e.g. High Resolution Wide Swath, TOPSAR, Mosaic, etc.).
•    Definition and development of software tools for computing the key performance parameters of SAR Instruments (e.g. resolution, swath width, ambiguity to signal ratios, NESZ, radiometric resolution, radiometric accuracy, etc.), in both conventional and unconventional acquisition geometries, and for both standard and advanced SAR acquisition techniques.
•    Definition, implementation and maintenance of models and software tools for simulating the key SAR Instrument functionalities (e.g. antenna beam models for both active phased array SAR antennas and reflector based SAR antennas, models of SAR data compression algorithms, etc.).
•    Definition, implementation and maintenance of SAR Instrument RF budgets.
•    Definition, implementation and maintenance of SAR Instrument calibration budgets.
•    In the frame of the design phases of the programme, support to the SAR Instrument Architect and to the SAR System Engineers for defining the key architectural features and for establishing functional and performance requirements at levels of Instrument, assembly, equipment and unit.
•    Contribution to definition of radar programming rules and assessment of their impacts in terms of in-flight SAR Instrument performance.
•    In the frame of the verification and validation phases of the programme, support to the SAR Instrument AIV Engineer for assessing/evaluating performance on the basis of test results at levels of Instrument, assembly, equipment and unit.
•    Participation to meetings with the SAR Instrument design team.
•    Participation to meetings/reviews with both internal and external customers for aspects related to SAR performance results, analyses, simulations and models.
•    Preparation of documents and presentations.
•    Contribution to programme reports and minutes of meetings
