The high speed signal processing technology of wideband digital receiver

Dong Hui

Abstract

At present,wideband digital receivers with 1 GHz band width are hot spot of digital receiver research,and also the development direction for radar EW reconnaissance digital receiver.Several high speed signal processing technologies of wideband digital receivers,including monbit IFM technology,polyphase channelized technology,channelized digital receiver based on FFT and RF bandpass sampling microwave digital receiver,are discussed in detail.Finally,some technologies that need to be deeply researched are given.
