Abstract
A system and method for mapping a ground strip having an extended range swath includes a synthetic aperture radar (SAR) mounted on a moving platform. The ground strip is divided into columns that extend from the near-range edge of the ground strip. Each column contains two or more portions and has an azimuthal length equal to the radar's near-range beamwidth, W. Each column is sequentially illuminated while the platform moves through a distance, L , (equal to the near range beamwidth). During column illumination, portions within the column are sequentially mapped by altering the depression angle, &phgr;, of the radar beam. Each portion is SAR mapped using a respective SAR aperture length with the sum of aperture lengths for the column being less than or equal to the distance the platform moves during illumination. The resultant maps are mosaicked together to produce one contiguous SAR map of the ground strip.
