摘　　要：为了验证雷达系统的抗干扰性能,利用SystemVue软件的专用雷达模型库构建雷达的全系统模型,仿真出各个分系统对雷达信号的处理功能,分析有干扰的雷达信号经过各级处理环节后的信号特征,并使用通用的仪器设备搭建起半实物仿真系统对各分系统进行实验验证。经实验可知,由SystemVue编辑并下载至仪器产生的雷达信号具有信号纯度高、相位噪声小、调制宽带可达2GHz,信号场景与真实干扰情况比较贴近的特性,满足雷达设计研制阶段的需求。In order to verify anti-jamming capability of radar,a global radar system model is established by using special radar model database of SystemVue software.By using the radar system model,signal processing function of each radar subsystem is simulated;features of radar signal in jamming after each processing link are analyzed;experimental test to each subsystems is verified through hardware-in-loop simulation system set up by general apparatus.Test results show that simulated radar signal generated by SystemVue edition and downloaded to the apparatus has the characteristics of high signal purity,low phase noise;modulated bandwidth can be up to 2GHz,and simulated scenario is closed to the real jamming situation,which can satisfy the requirement in radar design and development.
