<p>An interferometric synthetic aperture radar system for producing a highly precise three dimensional SAR image comprises a synthetic aperture radar system having two antennas separated by a predetermined separation distance which generates data comprising complex image pairs (A2k, A2k+1) representative of an image scene. Further provided are processing means for processing (21-24) the data comprising the complex image pairs (A2k, A2k+1), for calibrating (21) the data comprising the complex image pairs (A2k, A2k+1) to provide calibrated data, for processing (22) the calibrated data to generate a low ambiguity SAR elevation map, for processing (23) the low ambiguity SAR elevation map to provide an enhanced SAR elevation map, and for processing (24) the enhanced SAR elevation map to produce a precise three dimensional SAR image. <IMAGE></p> |
