Abstract :
The problem of increase of radio-telescope (RT) use efficiency in mm radiowaves range at supervision of the removed cosmic radio-sources (RCR) is considered. The problem consists that at pointing RT dishes system (DS) on RCR arise not compensated DS elements deformations. It results in distortion of distribution electromagnetic (EM) fields on an input of radio receiver (RR). The technique of restoration of true EM field distribution is offered by row scanning of some space area in which the finding of observable object is supposed.
