反射计测量目标反射特性方法分析

An Analysis of the Method for Reflectometer Measuring Target Reflection Characteristics

反射计是测量反射系数的仪器。通过分析目标反射特性测试方法、反射计工作原理和由反射计组成的测试系统,得出反射计可以用于目标反射特性测量的结论,并给出测量方法、计算公式、应用特点等。与连续波法、双天线法比较,得知反射计本质上相当于单站法测试系统中部分模块的集成,能采用单站法的测量系统就可用反射计测量。又对一种反射计法脉冲测试系统分析,进一步说明反射计可用于脉冲测试系统中。

Reflectometer is an equipment for measuring the reflection coefficient. By analyzing the methods of testing the target reflection characteristics, working principle of the reflectometer and the testing system composed of reflectometer, it is concluded that the reflectometer can be used to the target reflection characteristics measurment. The measurement method, calculation formula, application characteristics, etc are given. The compa- rision with the continuous wave method and double-antenna method shows that the reflectometer essentially is equivalent to a integration of single-station method testing system module. The measurement system which can use single station can be used for reflectance measurement. The analysis of pulse testing system using the reflec- tometer further shows that the reflectometer can be used for pulse test system.
