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

Rethinking of Underwater Image Restoration Based on Circularly Polarized Light

Photonics
Polarimetric imaging technology plays a crucial role in de-scattering, particularly in the field of underwater image restoration. Circularly polarized light (or the underlying circular polarization memory effect) has been proven to better preserve the ...
