RadarConf20-2020 IEEE Radar Conference, Sep 2020, Florence, Italy. pp.1-6, ⟨10.1109/RadarConf2043947.2020.9266569⟩

Radars can be used as a non-invasive solution to monitor the vital signs of patients. The heart and respiratory rates are generally extracted by analyzing the phase variations of the radar signal, thus motivating the use of millimeter-waves. This, ho

Non-Uniform Wavelet Sampling for RF Analog-to-Information Conversion

Autor: Michael Pelissier, Christoph Studer

Publikováno v: IEEE Transactions on Circuits and Systems I: Regular Papers, 65 (2)

Feature extraction, such as spectral occupancy, interferer energy and type, or direction-of-arrival, from wideband radio-frequency (RF) signals finds use in a growing number of applications as it enhances RF transceivers with cognitive abilities and

Diffraction Modeling and Imaging of Sand Injectites

Autor: R.L. Hartstra, T.J. Moser, Michael Pelissier, M. S. Jaya, D. Brethaut

Publikováno v: Proceedings.

Summary In this paper we use a conceptual model to investigate the diffraction response of sand injectites. Unlike conventional seismic attributes derived from a migrated image using a local averaging process, the diffraction image provides the full

International audience; In RF receivers nonlinearities are inherent to analog processing. This is the result of strong signals presence close to the bandwidth of the signal of interest, or a power excess of this signal. Both cases greatly deteriorate
