Jean-Pierre Le Cadre est né le 29 janvier 1953 à Elven dans le Morbihan en Bretagne. Jean-Pierre a commencé sa carrière de chercheur par une thèse de 3ème cycle en automatique et traitement du signal au laboratoire du Brusc en relation avec le Cephag, thèse qu'il soutient en 1982 à l'Institut National Polytechnique de Grenoble. Jusqu'en 1989, il est au GDRSM. Il obtient sa thèse d'état de l'INPG en 1987. Jean-Pierre rejoint l'Irisa en 1989 en tant que chercheur CNRS. Il sera successivement membre des équipes de recherche AS, Sigma-2, Vista et Aspi. Il a tout d'abord apporté des contributions importantes dans les thématiques suivantes: le traitement d'antennes haute résolution; l'analyse spatio-temporelle de sources en mouvement, qui lui vaudra le prix « Signal Processing best paper award » avec O. Zugmeyer (doctorant) en 1993; l'extraction de pistes et la trajectographie. Ses centres d'intérêt ont en fait significativement évolué depuis ses débuts et se sont situés, entre autres, dans les domaines de l'analyse des systèmes de détection et de poursuite, de l'association de données pour le suivi de cibles multiples, de la recherche opérationnelle ou de l'analyse d'événements et d'activités dans des séquences d'images.

Jean-Pierre a publié plus de 50 articles dans des revues et a formé également de nombreux doctorants. Il s'est investi dans le GDR ISIS, a eu des collaborations régulières académiques et industrielles aux niveaux national, notamment avec l'Onera, le Cesta, la DCN, Thomson-RCM, Thalès Systèmes Aéroportés, européen et international.

Jean-Pierre devait se rendre prochainement à Seattle à l'occasion du congrès Fusion'2009 pour recevoir le Prix « IEEE Barry Carlton Award » pour l'article écrit avec un de ses étudiants Thomas Bréhard «Closed-form posterior Cramer-Rao bounds for bearings-only tracking » paru dans IEEE Transactions on AES.

Jean-Pierre Lecadre est décédé le 1er juillet 2009.

J.-P. Le Cadre was born in Elven, on January 29, 1953. He received the M.S. degree in Mathematics in 1977 (Rennes) , the "Doctorat de 3ème cycle" in 1982 and the "Doctorat d'Etat" in 1987, both from INPG, Grenoble.

From 1980 to 1989, J.-P. Le Cadre worked at the GERDSM (Groupe d'Etudes et de Recherche en Detection Sous-Marines), a laboratory of the DCN (Direction des Constructions Navales), mainly on array processing. In this area, he conducted both theoretical and practical researches. In particular, he participated to the practical evaluation of high resolution methods on real data (towed arrays). Since 1st October 1988, he is with IRISA/CNRS (National Center for Scientific Research). Since 1st October 1996, he is a CNRS senior researcher ("Directeur de recherche"). He has been member of the following research groups: AS (1988-1995), Sigma-2 (1996) , Vista (1997-2008) and Aspi (2009). Over these years, his interests have moved towards a variety of topics including system analysis, detection, data association, operations research, tracking, information fusion and sensor networks.

J.-P. Le Cadre is the author of over 50 published journal papers and book chapters in these areas and supervised/co-supervised over than 15 PhD students. He received (with O. Zugmeyer) the SIGNAL PROCESSING best paper award (1993). He is recipient of the IEEE BARRY CARLTON AWARD 2008 (with T. Bréhard) for the paper "Closed-form Posterior Cramér-Rao Bounds for Bearings-Only Tracking" (IEEE Trans. on Aerospace and Electronic Systems, Vol. 42, no. 4, pp. 1198-1223, October 2006) and the Best Student Paper Award (with A. Ickowicz) of the Int. Conf. Intelligent Sensors, Sensor Networks and Information (ISSNIP'08) for the paper "Target Tracking within a Binary Sensor Network".

He is Area Editor (Target Tracking) of Journal of Advances in Information Fusion (ISIF) since 2002.

J.-P. Le Cadre is TPC member and award committee member of FUSION (since 2000) and TPC member of several conferences (RADAR, ICIF, COGIS, NATO (``Target Tracking and Sensor Data Fusion for Military Observation Systems'' 2003), IDC, ...). He was technical chairman of COGIS'2007, ADFS' 97 and Gretsi'97 and member of the organization committee of Fusion'2000. J.-P. Le Cadre was head of the organization committee of Gretsi'99. He was awarded as AUTOMATICA outstanding reviewer (2005). He is a member of various societies of IEEE and was Guest-Editor of special issue "La calibration d'antenne", Traitement du Signal, No 5, 1993. J.-P. Le Cadre served as reviewer for several journals in the areas of tracking, information fusion and operations research.

J.-P. Le Cadre is a member of the evaluating instance for "Space, Observation, Intelligence and UAV" (DGA) (2007-2008) and he was deputy member of the committee (Commission de spécialistes) of the 61th section ("Signal Processing and Automation") at University of Rennes 1 (2005-2007). He was co-coordinator of the GRECO ("Signal and Image Processing") Working Group "Multidimensional Signal and Antenna" (1988-1990) and coordinator of the GDR ("Signal Image Processing") Working Group "Antenna" (1991-1996). He is involved in activities of the GDR ISIS and involved in several national and European projects. He collaborates with companies including Onera, Cesta, DCN, Thomson-RCM, Thalès Systèmes Aéroportés ...

J.-P. Le Cadre participated in teaching courses for the masters students: DEA "Signal and Telecommunications" ("Digital filtering" and "Antenna Processing" / Speciality "Signal") (1990) ; DESS "Digital Images" (Speciality "Optimization") (1990) ; DEA "Signal, Telecommunications, Image and Radar" (Speciality "Signal") (1991-1994) ; DEA "Signal, Telecommunications, Image and Radar" ("Antenna Processing, Trajectography and Tracking" / Speciality "Signal") (1995-2002) ; Master 2 Research "Signal, Telecommunications, Image" ("Distributed Tracking, Data Association, Estimation via MCMC Methods") (2003-2009).

Jean-Pierre Lecadre passed away on July, 1st, 2009.
