摘要
FIELD: radio engineering.;SUBSTANCE: object is affected by test signal, response signal is received from object, after response signal, object is affected with additional test signal, response signal is delayed for test signal in delay line, time of signal delay in which is selected to be equal to time span between start of test signal and start of additional test signal, then output signal of delay line is let through first linear filter, and response signal of object to additional test signal is let through second linear filter and difference of signals at outputs of first and second filters is recorded, while relation of transfer characteristics of first and second linear filters is selected to be equal to relation of spectrums of additional test signal, as zero time moment, beginning of test signal is taken, during calculation of spectrum of additional test signal as zero time moment, beginning of additional test signal is taken. In particular case, difference of output signals of first and second linear filters is let through the third linear filter.;EFFECT: higher efficiency, broader functional capabilities.;2 cl, 6 dwg
