Abstract
Способ выделения сигнала шума источника из суммарного шума, включающий раздельный прием шума источника и суммарного шума, приведение масштаба времени сигнала суммарного шума к масштабу времени сигнала шума источника и измерение параметров спектра результирующего сигнала, отличающийся тем, что после преобразования временного масштаба сигнала суммарного шума дополнительно осуществляют фильтрацию в полосе частот, равной ширине сформированной дискретной спектральной составляющей, и выполняют инверсное преобразование временного масштаба отфильтрованного сигнала.The method of extracting the source noise signal from the total noise, including separately receiving the source noise and the total noise, bringing the time scale of the total noise signal to the time scale of the source noise signal and measuring the spectrum parameters of the resulting signal, characterized in that, after converting the time scale of the total noise signal, filtering in a frequency band equal to the width of the generated discrete spectral component, and perform inverse time-scale conversion aba filtered signal.
