Abstract
In article the dependence of the relation signal/noise in radars with the synthesized aperture (SAR) from resolution is considered.
It is shown that the relation signal/noise does not depend on resolution on inclined range.
The proof of increase in the relation signal/noise at reduction of an element of surface on traveling range due to increase in an interval of synthesis is provided.
It is shown that brightness of the radar image does not depend on resolution, and the contrast with reduction of an element of surface increases in connection with increase in the relation signal/noise.
