Aimed at the requirement of the radar system test,the construction method of injection type radar test system is analyzed,and the key technology is deeply studied. The amplitude and phase control network is used to establish pattern matching system,and the antenna pattern simulation is realized under a certain driving model. The method of digital orthogonal mixing and convolution is used to realize the target echo signal simulation. The way of wave function modulation VCO is used to realize noise jamming signal simulation. The methods proposed can enhance the electromagnetic environment pertinence and fidelity of radar test system.
