Способ автокорреляционного приема шумоподобных сигналов, заключающийся в перемножении принимаемого сигнала с опорным сигналом, отличающийся тем, что измеряют длительность принимаемого сигнала, осуществляют частотное детектирование принимаемого сигнала, выделяя тем самым моменты скачкообразного изменения фазы, определяют количество и величину тактовых периодов, опорный сигнал формируют путем задержки принимаемого сигнала на время τ з1=К1τ э, кратное тактовому периоду τ э, выделяют суммарное напряжение, перемножают его с принимаемым сигналом, задержанным на время τ з2=К2τ э, кратное тактовому периоду τ э, выделяют напряжение разности частоты, перемножают его с принимаемым сигналом, задержанным на время τ , которое периодически изменяют по линейному закону, выделяют низкочастотное напряжение, пропорциональное автокорреляционной функции, сравнивают его с пороговым уровнем, при превышении порогового уровня измеряют циклический сдвиг, по которому определяют кодовую структуру принимаемого сигнала.The method of autocorrelation receiving noise-like signals, which consists in multiplying the received signal with a reference signal, characterized in that the duration of the received signal is measured, frequency detection of the received signal is carried out, thereby highlighting the moments of phase jump, determine the number and magnitude of the clock periods, the reference signal is formed by delay the received signal at time τ P1 = K 1 τ e multiple of the clock period τ e, allocate total power, is multiplied with its accept m signal delayed by time τ s2 = R 2 τ e multiple of the clock period τ e is isolated voltage of the frequency difference, multiply it with the received signal delayed by time τ, which is periodically changed in a linear fashion, emit a low-frequency voltage proportional to the autocorrelation function compare it with a threshold level; when the threshold level is exceeded, a cyclic shift is measured, which determines the code structure of the received signal.
