ABSTRACT
The real-time processing of synthetic aperture radar (SAR) data has a high requirement for the processor, which is difficult problem in SAR processing. With rapid development optoelectronic devices, traditional electrical can be converted into to improve speed. In this paper, new type optical device proposed speed data. help spatial light modulator (SLM), initial signal and matched filter function are loaded on input plane spectrum 4f system, respectively. Using an lens with Fourier transform, transform inverse carried out realize fast imaging SAR. theory, light. Compared methods such as range-Doppler (RD) algorithm, it no longer necessary carry one-dimensional but matching filtering azimuth range system at same time. way, not introduce cylindrical lens, only spherical needed Finally, two-dimensional built obtain image real
