ABSTRACT:
A detector for detecting a communication pulse in the presence of noise is disclosed having a transmitter for transmitting a communication pulse of carrier frequency having a main pulse portion and a pre-pulse portion, the pre-pulse portion being of substantially opposite phase to the main pulse portion, a receiver for receiving the communication pulse, a correlation signal circuit connected to the receiver for providing a correlation signal, the correlation signal having first and second slopes in response to the communication pulse, the second slope being steeper than the first slope, and a comparator connected to the correlation signal circuit for providing a pulse detection output signal when the correlation signal reaches a predetermined threshold, the threshold being set at level to detect the correlation signal at a point on the second slope.
