Abstract: A signal processor which operates on an incoming signal to separate the signal into locally compact wavelets in the time frequency domain is described. The processor includes means for separating an incoming signal into a plurality of signals, with said signals occupying one of a corresponding plurality of channels, with each channel having a predetermined passband characteristic. The processor further includes means for scaling the filtered signals from the plurality of channels by an estimate of background noise in the filter data and detector means fed by said plurality of scaled signals for integrating coherent components of said filtered scaled signals.
