摘要：

There is under consideration a combined influence of the transients in the filters of the radar system selective circuits, non-equidistance of the taken readings and divergence of the beams at the distance up to the Earth surface reflecting elements that is comparable with a synthetic antenna aperture value. There is taken into account influence of the above-mentioned factors on the resolution capability of the radar system for the Earth remote sensing. The transients lead to swinging of the SAR antenna pattern; the other indicated factors result in widening of the synthetic antenna pattern. There are given the corresponding relationships and diagrams that make it possible to take into account the influence of the above-mentioned factors and determine the ways for reduction of the destructive factors influence on the synthetic antenna pattern.
