Abstract

In this paper a method of high frequency random signals correlation function in a real time has been grounded. It is shown how the time step delay is organized by using coupled strobe pulses whose repetition frequency differs in exactly determined value. A high frequency converter is related to a low frequency correlator using a spectrum "compression" transformation, which retains the unchanged information of the high frequency random signals correlation function. Simultaneously, (in real time) there is obtained a set of correlation function values out of which there has been formed the measured function graph. Having performed a Fourier transformation, we obtain frequency characteristics of the investigated signals.
