Abstract

Sophisticated signal processing is used in synthetic-aperture radar (SAR) systems to yield radar imagery with fine spatial resolution. Coherent optics has played a critical role in SAR signal processing for two decades and continues at present as the standard by which other SAR signal processors are measured. The signal processing operations which are required in SAR systems include display of the signal spectrum, spatial filtering, pulse compression, and post-detection integration. Depending upon the configuration of the radar itself, these may be required as one-dimensional or two-dimensional operations. In an optical processor, they are com-bined with imaging steps to move the signal to various locations in the processor, at which points these operations are implemented. Laser-illuminated spheres, cylinders and combinations thereof perform the signal processing operations. The signal processing requirements of SAR system are reviewed in this paper, and the manner in which elementary coherent optical configurations can be employed to satisfy these requirements is illustrated.
