Design and Realization of MF Ship-borne Radar Signal Simulation

In order to meet the all life cycle application from approving,designing,testing,toevaluating and training of ship-borne sensor or weapon,the paper discusses the architecture andcomposition of MF signal simulator system for a new ship-borne warning detection and tracking radar.With the introduction of system function and technical index,the paper focuses on application of softwareradio in MF radar signal simulation,and key technologies of radar EM environment and target echosimulation including target track simulation,target echo simulation,noise signal simulation,radarreceiving antenna simulation,and radar antenna orientation simulation.A method integrating softwareradio technology with software and hardware is used to realize living simulation of MF radar signal undercomplex sea battlefield EM environment.
