AnapproachisproposedtorealizeadigitalchannelizedreceiverinthefractionalFourierdomain(FRFD)forsignalinterceptapplications.ThepresentedarchitecturecanbeconsideredasageneralizationofthatinthetraditionalFourierdomain.Sincethelinearfrequencymodulation(LFM)signalhasagoodenergyconcentrationintheFRFD,bychoosinganappropriatefractionalFouriertransform(FRFT)order,thepresentedarchitecturecanconcentratethebroadbandLFMsignalintoonlyonesub-channelandthatwillpreventitfromcrossingseveralsub-channels.Thustheperformanceofthesignaldetectionandparameterestimationafterthesub-channeloutputwillbeimprovedsignificantly.Thecomputationalcomplexityisreducedenormouslyduetotheimplementationofthepolyphasefilterbankdecomposition,thustheproposedarchitecturecanberealizedasefficientlyasintheFourierdomain.Therelatedsimulationresultsarepresentedtoverifythevalidityofthetheoriesandmethodsinvolvedinthispaper.
