Stripmap Holographic Aperture Ladar

We have come to call this area of research Holographic Aperture Ladar because we are working in the optical regime where only time averaged intensity records are possible. Most likely then, by using 2D interferograms recorded in either the pupil or image planes, we will reconstruct (digitally) and stitch together the complex pupil plane field segments found for each data collection site. However, while the notion of reconstructing complex fields from interference records is generally reminiscent of holography we do not claim that traditional holographic methods for determining the field segments must necessarily be employed, or are that they are even required. In fact, in this paper we will assume that the complex pupil plane field segments are available to us with out regard to how they were obtained.
