摘　　要：对单脉冲二次雷达工作原理作简要介绍,分析天线波瓣外部测量法与内部测量法的优缺点以及波瓣发生变形产生的后果,从而对外部测量法进行相应改进。使用振幅-相位法测试二次雷达天线水平极化图和垂直极化图,并给出幅相不一致和交叉极化影响的解决方法,最终设计了一套二次雷达天线极化测量系统。该系统为民航雷达检测中心的建设提供理论与实践指导。The principle of Monopulse Secondary Surveillance Radar （MSSR）, the merits and disadvantages of external method measurement and internal method measurement are introduced. The result of on pattern distortion working is given, and the external method is improved. Using amplitude phase method to measure the HPD/VPD of MSSR, the solution for am- plitude and phase discordance and cross polarization impac are provided. A set of polarization measurement system is designed. This can be applied for the centre of civil radar detection construction and the theoretical and practical guidance are provided.
