FIELD: radio location. SUBSTANCE: aerial of radar installation being disposed vertically is shifted along the horizontal line along the axis of aerial system relatively the other motionless aerial in distance range from R1= λN/2 to R2= λ(N+1)/2 by means of electric drive, controlled by output voltage of signal phase detector of total and different receiving channels. Angle of position of low-height target is determined from the equation given in the description of the invention. EFFECT: improved precision; improved reliability. 1 dwg
