ABSTRACT:
In a receiving apparatus for detecting the presence or absence of periodically keyed random modulated signals, there are provided a pair of separate and distinct detection channels. One channel produces a real signal having clock line components and the other channel produces a decorrelated imaginary signal having no clock line components. The real and imaginary signals having carrier wave interference signals are processed in a Fourier transform device and a post processor to cancel out the carrier wave interference signals and to provide only a clock signal output when periodically keyed random modulated signals are being received.
