FIELD: radio measurement. SUBSTANCE: method of measurement of nonechoing of rooms in centimetric and millimetric ranges of lengths of electromagnetic waves is based on emission of electromagnetic wave with frequency changing in time by transmitting aerial, on reception of it with receiving aerial, on measurement of emitted and received powers. In this case directivity diagrams of transmitting and receiving aerials are chosen equal. Method also includes determination of dependence of gain factor of aerial on frequency, extraction of maximum and minimal values of this factor and computation of nonechoing factor by formula specified in description of invention. EFFECT: improved authenticity of measurements. 1 dwg
