摘　　要：采用极化扭转式卡氏天线、四喇叭馈源和波导混合环式和差网络实现了8 mm波快速扫描单脉冲天线。给出了天线各部分的设计、公差分析和仿真。由于设计时进行了详细的公差分析,样机几乎未经任何调试,便全面满足设计要求,主要指标与仿真结果非常吻合,表明给出的设计方法和公差分析对工程设计有较强的指导意义。A fast scanning mm- wave monopulse antenna was realized by using Cassegrain antenna with twist - reflector, four horn feed and wavegnide hybrid - ring sum and difference network. Design, error analysis and simulation of the antenna are presented. Because of analyzing the errors detailedly, the experimental results of prototype without nearly any adjusting agree with design value well. It vrefies that the methods of design and error analyzing are available for engineering application.
