Abstract
A real time SAR processing system for processing synthetic aperture radar (SAR) return signals and a method for real time processing of SAR return signals. The real time SAR processing system for processing synthetic aperture radar return signals comprises a light source (1) for generating a coherent, plane electromagnetic wave; light modulation means (2) for modulating the incident wave according to the radar return signals and outputting a modulated wave; and optical processing means (3) for submitting the modulated wave to an optical signal processing for radar image reconstruction. The light modulation means (2) comprises a plurality of addressable pixels (30) which are controlled based on the radar return signals. Light detection means (4) for detecting the processed wave and generating a corresponding electrical radar image signal are provided.
