J F HjelmstadJens Hjelmstad was born in Gudbrandsdalen, Norway. He graduated from the Norwegian University of Technology, Trondheim in 1979 with a thesis on the detectability of targets against sea background. From 1979 to 1980 he worked at the Norwegian Defence esearch Establishment with high speed spread spectrum communication systems. In 1980, he joined the Environmental Surveillance Technology Programme of the Royal Norwegian Council for Scientific and Industrial Research. His research interests lie in the area of new radio science concepts utilising space, time and polarisation processing. Hjelmstad has contributed significantly to the communication and radar communities through the NATO, URSI, IEE and IEEE scientific organisations. He has published papers in the fields of adaptive communication spread spectrum systems and adaptive multifrequency radar systems, and presented unifying theories to the integrated operation of communication and radar systems for remote sensing and information transfer. Hjelmstad has been involved in technological development programmes for wideband spread spectrum communication systems, environmental surveillance and data collecting systems, airborne and landbased radars for sea surface measurements and adaptive air surveillance radars.
