Interferometric radiometer |
摘要 |
A space-borne interferometric radiometer for imaging a radiation emission from a target scene (ED), comprising: a plurality of receiving elements arranged in a two- or three-dimensional array (REA); first signal processing means (SP 1 ) for computing a two-dimensional set of samples of a visibility function by pair-wise cross-correlating signals received by said receiving elements; and second signal processing means (SP 2 ) for reconstructing an image from said samples of said visibility function; characterized in that it further comprises means (ROT) for rotating said two- or three-dimensional array (REA) about a rotation axis (z) which is substantially directed toward said target scene (ED); and in that said second signal processing means (SP 2 ) are adapted for reconstructing said image from a plurality of two-dimensional sets of samples of said visibility function corresponding to different rotational positions of said rotating two- or three-dimensional array (REA) of receiving elements.
