Abstract

Essex has developed a hybrid acousto-optic/digital electronic processor, called Hawkeye^TM, that generates high dynamic range, high resolution range-doppler images from wideband radar returns. The processor is described and results of laboratory tests of a partially completed breadboard version are presented. Key capabilities of this processor are: high dynamic range to detect small cross section targets in a severe clutter background; large image sizes of 1024 or greater range bins by up to 128 doppler resolution bins; dynamically adjustable doppler resolution and dynamic reconfigurability of modules to switch between coarse range resolution covering a large range extent for acquisition mode to a fine resolution mode for target discrimination; the ability to accommodate time compression/dilation to eliminate blurring of moving targets in high resolution range-doppler images; and, the ability to efficiently combine multiple low bandwidth, low range resolution radar returns to obtain high range resolution range-doppler images. This is achieved in a compact, lightweight, and cost effective package.
