雷达散射截面测试的分段剖面处理

A Method of Elimination the RCS of the Section from the RCS of a Part of a Measured Object

针对雷达散射截面测试设备无法测量大尺寸目标模型 ,而采用分段测试方法时遇到的分段的剖面处理问题 ,提出了由三种不同方式封住分段的剖面测得的三组雷达散射截面值可得到该段的散射场的一种方法 .算例表明 ,该方法是有效的 .

The radar cross section (RCS) of the section is eliminated from the RCS of a part of measured object being too large to be measured by RCS test device. An efficient approach to obtain the electromagnetic scattered field is presented. In this approach, the section of the part of the object is covered with three different ways. Three RCS values measured respectively are obtained to solve the RCS of the part being out of its section. An example is given and the result indicates that the approach is simple and effective.
