Published in 2019 at "IEEE Transactions on Instrumentation and Measurement"

DOI: 10.1109/tim.2018.2834098

Abstract: In this paper, we investigate the effect of frequency uncertainty in signals generated or measured by a microwave instrument on the resulting synthetic aperture radar (SAR) images, particularly for nondestructive testing (NDT) applications. Wideband SAR… read more here.

Published in 2017 at "Journal of the Acoustical Society of America"

DOI: 10.1121/1.4988788

Abstract: Detection thresholds tend to be lower when the spectral and/or temporal characteristics of the signal are predictable than unpredictable, particularly in an unpredictable masker. The present study evaluated the detrimental effect of frequency uncertainty and… read more here.
