Abstract

Using a 3D formulation of inverse synthetic aperture (ISAR), we show how the arbitrary formatting capability of a time- integrating 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 prominent points in the radar data itself assuming a rigid body object. The opto-electronic processor is particularly suited for generated image data such as found with ISAR since it can arbitrarily place data points as needed depending on the object motion without need of interpolations. The processor is a time-integrating architecture that uses direct laser diode intensity modulation for signal insertion, acousto-optic scanners for arbitrary formatting, and a modified Kosters interferometer for stable 2D Fourier transformation. The processor also automatically generates multi-resolution imagery as a by- product of its generation of the final fine resolution image. Thus, there is a sequence of values available for each image pixel that are available for enhanced multi- resolution image processing. This research is funded by the Office of Naval Research.
