This work considers methods of pinpoint targets visibility improvement against the background of an underlying surface and terrain features with respect to advanced radars in case of increasing a spatial resolution. There have been revealed peculiarities of a radar image which are characteristic of short-range radars with a high spatial resolution. This work also illustrates the phenomenon of interclutter visibility (IV) for a practically important case of clutter from an underlying surface; it also introduced a quantitative evaluation (measure) of such phenomenon.
