Presents a low intermediate frequency zero adaptive anti-interference module based on PI algorithm. It put forward a multichannel input pretreatment and output pretreatment realization structure. It can be simplified digital fluctuation frequency converter design, reduce resource consumption. Through the Doppler performance analysis, module does not introduce addition?al carrier Doppler and code Doppler.The inherent relation unchanged .Do not affect the ranging accuracy of a subsequent receiver.
