　　应信息与电子学院邀请，法国泰勒斯集团航空业务科学主管、副总裁Francois Le Chevalier教授于2011年11月4日上午在华体会体育4号教学楼233会议室开展了“21世纪学科前沿”学术交流活动，作了题为“Adaptive space-time diversity and wideband waveforms for active antenna radar systems”的学术报告。报告会由信息与电子学院曾涛教授主持，出席报告的有信息与电子学院院长龙腾教授及数十位教师和研究生。

　　Francois教授在报告中介绍了主动式天线系统。由于其广泛的业务和技术优势，主动式天线系统正在成为高性能的雷达系统的标准。然而它仍然有改进的余地：新的架构设计可以为未来的雷达系统提供更多的优势。Francois教授的报告图文并茂，深入浅出，与会师生认真听取了此次报告，并同Francois教授进行了热烈的讨论交流。 

　　通过这次学术交流活动，使与会人员受益匪浅，拓展了学术视野，对雷达天线系统中的有关技术有了更深入的了解，对选择研究方向和开展科学研究均有很大帮助。下午Francois还与我校从事相关研究的科研人员进行了进一步的学术讨论，并就将来的合作交流计划进行了磋商。

　　Biography:

　　François Le Chevalier is in charge of the Chair “Radar Systems Engineering” at Delft University of Technology (The Netherlands), and VP, Scientific Director of Thales Air Operations, in Rungis, France.   

　　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 the 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 focuses on space-time diversity and coding and wideband signal processing for RF sensors.
  He chaired the Scientific Committee of the International Radar Conference, Brest, 1999, and he has since been active in the Technical Program Committees of the major radar international conferences in Europe, America, and Asia.

　　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) and a Senior Member of IEEE, is the author of a book on “Radar and Sonar Signal Processing Principles” published by Artech House in 2002, and editor of the book “Non-Standard Antennas”, published by Wiley in 2011.
