Abstract :
A method for performing digital phase history processing of synthetic aperture radar (SAR) data using optical computers is proposed. The method has nothing in common with the old analog optical SAR processing methods (which used lenses), but is rather a totally digital (numerical) technique for computing the individual complex pixel values based on matrix-vector multiplications. The method can be expected to greatly increase the potential processing speed and coverage possibilities of high-resolution digital SAR systems
