Design and Realization of Radar Signal Environment Simulator

It is very important to build up a kind of complex signal environments by adopting a method of IF injection to improve and train operators under conditions of the complex electric warfare environments.This paper introduces a radar signal environment simulator.First,through analyzing target echoes,deception signals and jamming signals.an overall concept design and a modularization structure design plan for the simulator are proposed,and its performance is tested.The result shows that this simulator can generate echo,deception jamming,chirp jamming signal,barrage jamming,and interrupted-spotting jamming signal in real-time,and can switch over them in signal channels.The simulator has a great value for matching the design requirement well,and has practical value.
