ABSTRACT:
The presence of a pulsed radio frequency signal is detected by periodically sampling such signal with first and second sampling strobes in quadrature relationship. The first and second strobes are separately accumulated for a first period of time overlapping a second period of time during which the first and second strobes are also accumulated. The four sums resulting from such accumulations are compared with a predetermined threshold level to determine the presence of the pulsed radio frequency signal.
