A tiling of multi-SLM is used in full resolution optical SAR data processor

Synthetic Aperture Radar (SAR) is a powerful tool for alltime and all-weather imaging. As the technology developed, the resolution of SAR image is required much higher, and the processing time is required shorter. Traditional DSP processor is difficult to process the high resolution complex SAR data of 3 meter and 1 meter, or even high. The optical processor performs the most promising capability, since the Fourier lens provide inherent parallel computing. In addition, it can perform the Fourier transformation at the speed of light. This paper proposes a tiling project to perform the full resolution SAR data imaging.
