초록 ▼

A radiometer (100) uses the fringe pattern of an interferometer (110) to scan a scene to produce a time record from which a high-resolution radio frequency, or other radiation, distribution of the scene can be reconstructed. A matched filter (120), or other means, transforms the time record according to a function of a signature of the determinable scanning motion relative to the fringe pattern. For many applications, the modulation transfer function (123) of an included matched filter is the complex conjugate of the Fourier transform of the signature that would be produced by a constant point emitter scanned by the lobes of the interferometer fringe pattern. Two-dimensional reconstructions may be provided for by multiple scans at different orientations. Alternatively, frequency scanning or another scanning technique can provide resolution orthogonal to the fringe pattern scanning motion. Focused distributions of multiple scenes and complex scanning motions are provided by appropriate selections of one or more signatures to process a given time record.

대표청구항 ▼

A radiometer for reconstructing the radiation distribution of a scene of noncoherent multiple emitters comprising: an interferometer further comprising; first and second antennas, each of the antennas producing individual time records in response to radio frequency emissions from the scene and means coupled to the first and second antennas for combining the individual time records to produce an interferemeter time record of the scene, said interferometer also having a predetermined fringe pattern with a series of sensitivity lobes with different widths; scanning means for effecting determinable relative movement between said fringe pattern and said scene so that a predetermined plurality of said lobes scan said scene; signature means for providing a signature of said determinable scanning motion relative to said predetermined fringe pattern; and transform means for reconstructing said distribution from said interferometer time record according to a function of said signature, said function being selected so that its resultant is a reconstruction of the radiation distribution of said scene.
