Design of digital channelized broadband receiver for high speed frequency hopping signal

Abstract： As a new type of communication system，FH communication has strong characteristics of anti-interception,anti-search,ant-interference and anti-antagonism. FH communication system is adopted in the tactical information distribution system,ground and shipborne and airborne FH radio stations and identification friend or Foe systems of the United states and NATO countries,which has high confidentiality and anti-interference performance.In view of the characteristics of high speed FH signal with wide frequency band,many frequency points and fast frequency hopping speed,this paper proposes to use two pieces of ADRV9009 RF agility chip to transform the high speed FH signal into zero IF signal,and then send it to PFGA through polyphase filtering digital channelization to complete the signal receiving and processing.The design not only simplifies the whole signal front-end wideband reception process,reduces the volume of the front-end analog channel receiving equipment,and reduces the power consumption of the system,but also greatly increases the flexibility of the syetem,and improves the detection and identification probability of high-speed frequency hopping signal in the end.
