The calculation methods of received signals must be corrected for the finite durations of reflected pulses. The reflected space was circle with radii equal to products of two pulse durations and distance tj the reflected planes. The amplitude pulse dispersions dependent from the time intervals counted off the pulse beginnings. It was proportional the two power time intervals for small ones and the intervals with its increasing. The moment crossing fixation gives the possibility for estimations the roughness mean size.
