Abstract

A real-time aircraft synthetic-aperture radar (SAR) image processor using charge-coupled device (CCD) technology has been developed. Both range and azimuth convolution are accomplished using CCD transversal filtering in the analog domain. The computational equivalency of a CCD transversal filter to comparatively more complex digital processing implementations provides significant reductions in processor power, weight, size, and cost requirements. This paper describes the results of the aircraft CCD SAR image-processor development work to date.
