The Design And Implementation Of Missile-borne Millimeter-wave Seeker Radar Signal Processing System

With the advantages of small aperture antenna,narrow beam,large bandwidth and many others,millimeter-wave(MMW)Radar is widely used in seeker Radar.Based on the design ideas of signal processing system,the scheme of hardware platform,the algorithm of signal processing system and the implementation of FPGA are designed in detail in this dissertation.This dissertation mainly completes the design of the MMW Radar signal processing system and the FPGA implementation.Firstly,the research background of MMW Radar is introduced in detail.Secondly,the theory of Radar signal processing algorithms is described,and the design and simulation results of the algorithm are given.Thirdly,according to the design ideas of the system,the work mode,work flow and algorithm of the system are designed in turn.The architecture and hardware scheme of the signal processing system are given according to the mode and flow.The hardware scheme of FPGA+DSP is adopted,and the signal processing is flexible.Then,the signal processing algorithm is designed and simulated by FPGA,and the design and simulation results are given,including AD sampling module,digital quadrature demodulation module,pulse compression module,moving target indicator module,moving target detector module,constant false alarm module and SerDes and SRIO interface communication module.Finally,the signal processing algorithm and communication interface module are debugged on the system hardware platform.By experimental verification,the system realizes the whole process of the radar signal processing algorithm,correctly detects the distance,speed and other information of the target and meet the system design requirements.
