Abstract:
A synthetic aperture radar (SAR) image of a wide coverage area is acquired during a frame containing a first plurality of ambiguities induced in the SAR image from radar scatterers within the area. The area is illuminated with radar pulses and a segmented receive antenna oriented towards the area. The segmented receive antenna has a second plurality of sub-apertures, where the second plurality of sub-apertures is larger than the first plurality of ambiguities. Each sub-aperture has its own receiver. The digital stream from each receiver is stored in a computer for the duration of the frame to obtain frame data. A SAR image is extracted from the frame data. The first plurality of ambiguities are identified from analysis of the frame data, and a correction is computed to account for the first plurality of ambiguities contained within the synthetic aperture image. The correction is applied to reduce distortions caused by the ambiguities in the SAR image.
