Abstract

A 3D formulation of inverse synthetic aperture (ISAR) is presented showing how the various geometry and motion parameters determine the image generation properties. We then show how the arbitrary formatting capability of an opto-electronic processor can be used to format the data in such a way as to focus the image. The focusing parameters are found from tracking prominent points in the radar data itself and using rigid body constraints imposed on the data. The opto-electronic processor is particularly suited for generated image data such as found with ISAR. The processor is a time-integrating architecture that uses acousto-optic scanners for arbitrary formatting and a modified Kosters interferometer for stable Fourier transformation. This research is being funded by the Office of Naval Research.
