FIELD: radio engineering.
SUBSTANCE: in the method, firstly, the current of potential meter beam is modulated by voltage of coherent heterodyne, then cross-period subtraction of broadband radio impulses is performed, signal amplitudes are limited below minimal noise level and one side band is filtered.
EFFECT: unevenness of potential meter target is prevented from influencing output signals.
