A cueing wideband digital receiver is presented for intercepting signals with higher probability.Channelization module is applied to its design for intercepting simultaneous signals with narrow bandwidth.And the noncoherent energy integration and the weighted digital instantaneous frequency measurement(WDIFM) find their application in the given design to detect and estimate signals of channelized output.Information,which can cue digital down converting the signal with variable bandwidth,is formed from adjacent channels decision.The improved performances of the proposed receiver,such as high sensitivity and high probability of interception,are verified by simulation results.
