Nuclear Quadrupole Resonance (NQR) is a radio frequency technique
offering an unequivocal method of detecting the presence of the
nitrogen isotope N-14, a common component in many forms of high
explosives, narcotics, and drugs. The NQR signal originates from the
interaction between the electric quadrupole moment of the nucleus
and the electric field gradient generated at the nuclear site by
external charges. During the talk, we will elaborate on the fine
structure of the NQR data model and on how it can be exploited to
improve the probability of detection for both single and multiple
sensor detectors. We will also discuss possibilities to counter the
typically significant radio frequency interference. Some further
information on NQR can be found at

BIOGRAPHY OF “ANDREAS JAKOBSSON”



ANDREAS JAKOBSSON received his M.Sc. from Lund Institute of
Technology and his Ph.D. in Signal Processing from Uppsala
University in 1993 and 2000, respectively. Since, he has held
positions with Global IP Sound AB, the Swedish Royal Institute of
Technology and King's College London; he has also been a visiting
researcher at Brigham Young University, Stanford University,
Katholieke Universiteit Leuven, and University of California, San
Diego. He is currently Professor of Signal Processing at the Dept.
of Electrical Engineering of Karlstad University, Sweden. He also
holds an Honorary Research Fellowship at Cardiff University. His
research interests include statistical and array signal processing,
detection and estimation theory, and related application in remote
sensing, telecommunication and biomedicine.
