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), a first signal processor (SP1) for computing a two-dimensional set of samples of a visibility function by pair-wise cross-correlating signals received by the receiving elements; and second signal processor (SP2) for reconstructing an image from the samples of the visibility function. The radiometer is further characterized in that it has the ability for rotating the two- or three-dimensional array (REA) about a rotation axis (z) which is substantially directed toward the target scene (ED) and in that the second signal processor (SP2) is adapted for reconstructing the image from a plurality of two-dimensional sets of samples of the visibility function corresponding to different rotational positions of the rotating two- or three-dimensional array (REA) of receiving elements.
An interferometric radiometer for imaging a target scene (ED), comprising:
A multi-band interferometric radiometer comprising a plurality of individual interferometric radiometers according to claim l, the two- or three-dimensional arrays of receiving elements of which (REA-53, REA-118,) REA-153, REA-380) are mounted on a common rotating structure (STR), each of said individual interferometric radiometers being adapted to operate in a different spectral band.
