前言雷达行馈源是雷达产品关键技术项目之一,它直接关系到雷达方案的成败。在选择方案时,某雷达行馈源总体方案有两种:一种是同轴线方案,这种方案比较成熟,但技术落后;另一种是大型平面组件方案,其主要特点是可靠性高、重现性好和防潮性能优越等。然而,由于技术复杂、要求高和难度大,因此以前尚未研究过。雷达行馈源中的天线、馈线等系统全部安装在转台上,且暴露在外面,所以要求行
Preface Radar line feed is one of the key technology projects of radar products, which is directly related to the success or failure of the radar program. In choosing a scheme, there are two kinds of general schemes for feeding a certain radar line: one is a coaxial scheme, which is more mature but lags behind in technology; the other is a large planar scheme with the main features of high reliability , Reproducible and moisture-proof performance and so on. However, it has not been studied before because of its technical complexity, high requirements and difficulty. Radar line feeds in the antenna, feeder and other systems are all installed on the turntable, and exposed to the outside, so request line
