Claim One:
1. A parameter encoder for receiving at least one wideband intermediate frequency (IF) channel of IF signals from a simultaneously intercepted plurality of IF channels each having a predetermined channel bandwidth, and for real-time detection of important IF signals of varying amplitude and frequency from said IF channel, comprising: a cascade of bandpass filters having filters grouped in a plurality of filter levels, each said filter level filtering said IF signals by dividing each IF channel bandwidth into a plurality of sub-band levels, each said sub-band level having a progressively narrower bandwidth than preceding sub-band levels; a pulse detection means for receiving said IF signals in a sub-band time multiplexed mode and for analyzing said IF signals to obtain IF signal parameters; a control processor means for determining the important IF signals according to the IF signal parameters; a channel arbitration means for selecting the IF channel corresponding to the important IF signal; and a pulse descriptor word (PDW) assembler means connected to said control processor means and said channel arbitration means for producing a pulse descriptor word for each said important IF signal.
