An imaging system uses wideband RF daylight created by plural narrowband RF illumination sources, to passively generate spectrally different sets of RF scattering coefficients for multiple points within a prescribed three- dimensional volume being illuminated by the narrowband RF transmitters. To correct fot the lack of mutual coherence among different RF illumination sources, the respective sets of scattering coefficient data are applied to a cultral feature extraction operator, to locate one or more strong cultural features spatially common to multiple images. For spatial points along the extracted cultural feature theoretical scattering coefficients are calculated. Differences between phase values of these calculated scattering coefficients and those of the collected and processed scattering energy are used to modify the measured scattering coefficient values for all points in the illuminated region.

L'invention concerne un système d'imagerie utilisant un éclairage de jour RF à large bande créé par plusieurs sources d'éclairage RF à bande étroite afin de générer passivement des ensembles de coefficients d'éparpillement RF spectralement différents pour de multiples points à l'intérieur d'un volume tridimensionnel prescrit étant éclairé par des émetteurs RF à bande étroite. En vue de corriger le manque de cohérence mutuelle parmi les diverses sources d'éclairage, les ensembles respectifs de données de coefficient d'éparpillement sont appliqués à un opérateur d'extraction de caractéristique culturelle, afin de localiser une ou plusieurs fortes caractéristiques culturelles communes sur le plan spatial à de multiples images. On calcule des coefficients d'éparpillement théorique pour des points spatiaux avec la caractéristique culturelle extraite. Les différences entre les valeurs de phase de ces coefficients d'éparpillement calculés et celles de l'énergie d'éparpillement traitée et collectée servent à modifier les valeurs de coefficients d'éparpillement mesurées pour tous les points de la zone éclairée.
