Partially adaptive filtering using randomized projections
Olivier Besson
This short note addresses the design of a partially adaptive filter to retrieve a signal of interest in the presence of strong low-rank interference and thermal noise. We consider…
A short overview of adaptive multichannel filters SNR loss analysis
Olivier Besson
Many multichannel systems use a linear filter to retrieve a signal of interest corrupted by noise whose statistics are partly unknown. The optimal filter in Gaussian noise requires…
Analysis of the SNR loss distribution with covariance mismatched training samples
Olivier Besson
We analyze the distribution of the signal to noise ratio (SNR) loss at the output of an adaptive filter which is trained with samples that do not share the same covariance matrix a…
Sub-pixel detection in hyperspectral imaging with elliptically contoured -distributed background
Olivier Besson, François Vincent
Detection of a target with known spectral signature when this target may occupy only a fraction of the pixel is an important issue in hyperspectral imaging. We recently derived the…
Adaptive Detection of Coherent Radar Targets in the Presence of Noise Jamming
Pia Addabbo, Olivier Besson, Danilo Orlando +1
In this paper, we devise adaptive decision schemes to detect targets competing against clutter and smart noise-like jammers (NLJ) which illuminate the radar system from the sidelob…
Design of robust radar detectors through random perturbation of the target signature
Angelo Coluccia, Giuseppe Ricci, Olivier Besson
The paper addresses the problem of designing radar detectors more robust than Kelly's detector to possible mismatches of the assumed target signature, but with no performance degra…
