Abstract
A proximity fuze radar system is described including a transmitter for transmitting a signal modulated by a pseudo-random noise code signal and a receiver for receiving signals including the modulated signal reflected by an object or target. The proximity fuze radar system further includes delay circuitry for delaying in time the pseudo-random noise code signal for providing a delayed noise code signal and circuitry for correlating a near range portion of the received signals with the delayed noise code signal and for providing base band signals. The proximity fuze radar system still further includes suppression circuitry for correlating a longer range portion of the received signals with the delayed noise code signal and for providing a rejection signal for summing the base band signals with the rejection signal to reduce the signal level of undesired signals. With such an arrangement, a radar system is provided having less susceptibility to undesired signals.
