【 摘 要 】

A synthetic aperture radar is usually a complex software and hardware package that allows obtaining images in the radio range comparable in resolution with optical systems. The advantage of radio waves is that high-quality photography takes place despite cloudiness and dark time of the day. The development of algorithms for this system type is rather complicated process; mathematical modeling is used for reducing its cost. This paper shows the applicability of approximation methods to calculate the scattered field for imaging of synthetic aperture radar. The disadvantages of these methods are also discussed.
