| Abstract: A synthetic aperture radar (SAR) image is produced by using all phase
histories of a set of phase histories to produce a first pixel array
having a first azimuth resolution, and using less than all phase
histories of the set to produce a second pixel array having a second
azimuth resolution that is coarser than the first azimuth resolution. The
first and second pixel arrays are combined to produce a third pixel array
defining a desired SAR image that shows distinct shadows of moving
objects while preserving detail in stationary background clutter. |
