This paper shows that space time adaptive processing (STAP) can be fruitfully applied also to ground based radar to simultaneously cancel clutter and e.m. interference (e.g.: jammer). This is demonstrated by processing live data recorded by a C-band phased-array radar demonstrator having three spatial channels and few tents of coherent received pulses. The processing is done by emulating, on a software program, a systolic algorithm which is amenable for parallel processing thus allowing to reach the real time requirement. This paper opens up the way to a more extensive application of STAP which, up to now, is limited only to radar on board of moving platform. In fact, it can find a role in ground based and ship borne radar where clutter and jammer are contemporaneously present in the radar echoes and their characteristics (e.g.: direction of arrival, power, spectral shape) are not known a priori.
Dr. Alfonso Farina - AMS
Alfonso FARINA (Fellow of IEEE and Fellow of IEE) received his doctor degree in electronic engineering from the University of Rome (I) in 1973. In 1974 he joined Selenia, now Alenia Marconi Systems, where he is a manager (since May 1988); since one year he is a member of the Chief Technical Office. Recently he has been appointed Scientific Director. In his professional life Alfonso has provided technical contributions to detection, signal, data & fusion, image processing for radar systems. He has provided leadership in many projects – also conducted in the international arena – in surveillance for ground and naval applications, in airborne early warning and in imaging radar. Since 1979, he has also been Professore Incaricato of Radar Techniques at the University of Naples; in 1985 he was appointed Associate Professor. He is the author of more than 270 peer reviewed publications and the author of books and monographs: Radar Data Processing (Vol. 1 and 2) (translated in Russian and Chinese), 1985-1986 ; Optimised Radar Processors, 1987 ; Antenna Based Signal Processing Techniques for Radar Systems, 1992. He has written the Chapter 9 on “ECCM techniques” in the Radar Handbook (2nd Edition 1990), edited by Dr. M. I. Skolnik of Naval Research Laboratory. He has been session chairman at many international radar conferences. He uses to lecture at universities and research centres in Italy and abroad; He also frequently gives tutorials at the Intl. Radar Conferences on signal, data and image processing for radar; in particular on multi-sensor fusion, adaptive signal processing, space time adaptive processing (STAP) and detection. In the 1987 He received the Radar Systems Panel Award of IEEE-AESS for development of radar data processing techniques. He is the Italian representative at the International Radar Systems Panel of IEEE-AESS. He has been the Italian industrial representative at the SET (Sensor and Electronic Technology) of RTO (Research Technology Organisation) of NATO. He has been in the BoD of the International Society for Information Fusion (ISIF). He has been nominated Fellow of IEEE with the following citation: "For development and application of adaptive signal processing methods for radar systems." He is a referee of numerous publications submitted to several Journals of IEEE, IEE, Elsevier, etc., He has also cooperated with the editorial board of ECEJ (Electronics & Communication Engineering Journal) of IEE. More recently, Alfonso serves as a member in the Editorial Board of Signal Processing (Elsevier). He is the co-recipient of the prestigious best paper award, entitled to Mr. B. Carlton, of IEEE Trans. on Aerospace and Electronic Systems for the year 2001. Alfonso has been the leader of the team that received the 2002 AMS CEO award for Innovation Technology. Alfonso has recently been the co-recipient of the AMS Radar Division award for Innovation Technology in 2003.
Dr. Luca Timmoneri - AMS
Luca Timmoneri received the doctor degree in electronic engineering from the University of Rome, Italy, in 1989. In 1989 he joined Selenia S.p.A. now AMS (Alenia Marconi Systems), where he is currently the Leader of the Radar System Analysis Group of the Radar and Technology Division. His working interests span from the area of synthetic aperture radar (image formation and moving target detection and imaging), to space-time adaptive processing for AEW and ground-based radar, to parallel processing architectures with VLSI and COTS devices. He is presently involved in the areas of adaptive signal processing, detection and estimation with application to tri-dimensional ground and ship based phased array radar. He is the author of several peer reviewed papers (also invited) on journals and conference proceedings. He is the co-author of three tutorials on adaptive array and space-time adaptive processing presented at the intl. radar conference in Washington DC (1995) , Boston (1999) and Boston (2003). Dr. Timmoneri received the 2002 AMS CEO Award and the 2003 AMS MD Award for Innovation Technology.
