Paper Abstract

In this paper an infrared single element two-dimensional acoustooptic processor using a crystal of tellurium will be described, that can process to return echos of each pulse to form the image of the terrain illuminated by the SAR in real-time. This highly compact processor is designed to maintain a range and azimuth resolution of 2 m, will operate with an acoustic bandwith of 200 MHz for an acoustic drive-power of only 1 watt at the optic wavelength of 5 μm and will reach a dynamic range of the order of 40dB determined by the Hg Cd Te CCD array. This processor will control range and azimuth sidelobes below 40 dB, in a minimum detector integration time of 200 ms to resolve a 5 Hz Doppler frequency.
