interferometric radiometer.

摘要

Interferometric radiometer for imaging of a radiation emission of a target scene (ED), comprising: - a plurality of receiving elements (201, 202) for receiving said radiation, said receiving elements (201, 202) being arranged in form of a two-dimensional or three-dimensional network (OER); - first means of signal processing (SP1) to calculate a two-dimensional set of samples of a visibility function (V) of said radiation emission by cross-correlation in pairs of the signals received by said receiving elements (201, 202); and - second signal processing means (SP2) to reconstruct an image of the intensity (MI) of said radiation emission from said samples of said visibility function (V); characterized in that it further comprises means (ROT) for rotation of said two-dimensional or three-dimensional network of receiving elements (OER) around a rotation axis (z) that is practically directed towards said target scene (ED); and because said second signal processing means (SP2) are adapted to reconstruct said intensity image (MI) from a plurality of two-dimensional sets of samples of said visibility function (V), each of said sets corresponding of samples at a different angular position of said two-dimensional or three-dimensional rotating network (REA) of receiving elements.
