PolSAR Image Modulation Using a Flexible Metasurface with Independently Controllable Polarizations

Remote Sensing
Recent advances in time-modulated metasurfaces (TMMs) have introduced approaches for controlling target features in radar imaging. These technologies enable dynamic reconstruction of scattering center locations and intensities by flexibly manipulating ...

Polarimetric radar images

, 2014
Ce manuscrit concerne une synthèse de mes travaux de recherches menés au sein de l'Onera sur les images polarimétriques radar de télédétection. Un radar polarimétrique permet de mesurer un plus grand nombre de paramètres qu'un radar monocanal en exploitant la nature vectorielle de l'onde électromagnétique.

Polarimetric thermal imaging

, 2007
Passive infrared (IR) imagers, using intensity contrast for target detection, are often limited by low target-background contrast. Detecting stationary targets against cluttered backgrounds presents an even bigger challenge. Polarized signatures can be used as an additional discriminator, to improve target detection probability and reduce false alarm
