Biography:François Le Chevalier is in charge of the Chair “Radar Systems Engineering” at Delft University of Technology (The Netherlands), and Chief Scientist of Thales Air & Land Systems (International).

Mr. Le Chevalier began his career at the Office National d’Etudes et de Recherches Aérospatiales (Onera), where he initiated research on radar target and background signatures processing. In 1986, Mr. Le Chevalier joined Thomson-CSF (now Thales), where he pioneered French developments in adaptive digital beamforming and STAP radar systems demonstrations, and shared apertures and multisensor concepts design and validation. In 1998, he joined the Airborne Systems group, as Scientific Director, in charge of advanced research and developments coordination (airborne radars, electronic warfare, airborne mission systems). His current research activities include space-time coding for active antenna systems, and wideband unambiguous radar systems.

He has been active in- or chairing- the Technical Program Committees of most IEEE International Radar Conferences since Brest, 1999, has recently chaired the Technical Program Committee of EURAD 2012, Amsterdam, and has been the honorary Chair of SEE/IEEE International Radar Conference Radar 2014 in Lille, France.

An author of many papers, tutorials, and patents in radar and electronic warfare, Prof. Le Chevalier, an Emerite member of the Société des Electriciens et des Electroniciens (SEE), is the author of a book on “Radar and Sonar Signal Processing Principles” published by Artech House in 2002, editor of “Non-Standard Antennas”, published by Wiley in 2010, and co-author of “Principles of Modern Radar: Advanced Techniques”, published by Scitech, IET Publishing, 2012.


Title：Wideband Wide beam Motion Sensing
Abstract：The instantaneous bandwidth is a critical radar parameter, with direct influence on the performances, but also on the cost – this being especially true for active antenna systems, where multiple channels reception is generally implemented for taking full advantage of the flexibility. It is therefore important to consolidate an overall view of the expected benefits of an increased bandwidth, taking into account all possible effects.
In this tutorial, we will analyze the relations between range, Doppler, and angle, – including simultaneous transmissions, or colocated MIMO – , for detection and location of moving targets. The idea is to contribute to a better understanding of the benefits of widening the bandwidth for detection of moving targets, focusing not only on waveform aspects, but also on the velocity and angular measurement consequences.
Special attention will be given to the quality of the different sensor modes, evaluated through their ambiguity functions, and new results on mismatched and adaptive processing will be provided to demonstrate the effectiveness of the different solutions for small and slow targets detection at long range, in difficult environments.
Due to their wide range of operational and technical advantages, active antenna systems are now becoming a standard for high performance radar systems. However, this tutorial will show that widened bandwidths are also key to operational performance improvement. New architectures can be designed for future radar systems, with modern front-end capabilities taking full benefit from the available agility and diversity, for improved detection of targets and threat analysis in difficult environments.

Who should attend:
This course is intended for researchers, radar designers, and program managers interested in obtaining additional insight into active antenna radar systems capabilities.
Throughout the lecture, intuitive reasoning and simple examples will be preferred to analytical demonstrations to provide the audience with an insider understanding of the basic properties and trade-offs.
