Signal Processing for Radio Astronomical Image Formation
In recent years several very large radio telescopes have been built and some more are in the design process. These radio telescopes consist of thousands of elements and observe the universe with extremely high bandwidth. On the other hand the requirement to observe fainter objects makes the signal processing even more challenging. In this talk I will provide an introduction to signal processing in radio astronomy and describe some modern signal processing perspectives on the proper solutions.
Amir Leshem received the B.Sc. (cum laude) in mathematics and physics, the M.Sc. (cum laude) in mathematics, and the Ph.D. in mathematics all from the Hebrew University, Jerusalem From 1998 to 2000 he was with Faculty of Information Technology and Systems, Delft university of technology, The Netherlands, as a postdoctoral fellow working on algorithms for the reduction of terrestrial electromagnetic interference in radio-astronomical radio-telescope antenna arrays and signal processing for communication. From 2000 to 2003 he was director of advanced technologies with Metalink Broadband where he was responsible for research and development of new DSL and wireless MIMO modem technologies and served as a member of ITU-T SG15, ETSI TM06, NIPP-NAI, IEEE 802.3 and 802.11. From 2000 to 2002 he was also a visiting researcher at Delft University of Technology. He is one of the founders of the Faculty of Engineering at Bar-Ilan University where he is a professor and head of the communication track. In 2008-2009 he was a visiting professor at Deflt University of Technology and Stanford University.
From 2003 to 2005 he also was the technical manager of the U-BROAD consortium developing technologies to provide 100 Mbps and beyond over DSL lines. He was the leading guest editor a special issue of IEEE Journal on Selected Topics in Signal Processing, dedicated to signal processing for space research and for a special issue of the Signal Processing Magazine, dedicated to signal processing in astronomy and cosmology. He was an associate editor for IEEE Trans. on Signal Processing.
His main research interests include multichannel wireless and wireline communication, applications of game theory to dynamic and adaptive spectrum management of communication networks, array and statistical signal processing with applications to multiple element sensor arrays and networks, set theory, logic and foundations of mathematics.
