摘要： In a returned wave object detection receiving system, for receiving a wideband signal, means are provided for attenuating narrowband interference. A returned signal is split such that equal power broadband signals are applied to a plurality of channels. In each channel, the broadband signal is coupled through a narrowband filter and a linear amplifier in parallel with a detector and noise correlator. The narrowband signals are recombined in an adder having an output coupled to utilization means. Disabling means are coupled in each channel for disabling one narrowband channel in response to narrowband interference therein.
