摘要：

通过对现有的K波段微波功率敏感器校准方法的研究,提出了利用研制的偏置功率匹配器,采用传递标准法,组成了低反射系数等效信号源结构的新方案,实现了对K波段微波功率敏感器的准确校准,并对测量不确定度来源进行了分析与评定。

Abstract: Through analyzing the theory of microwave power sensor calibration system, a form scheme has been brought forward by making use of bias power matching box, transfer standard method and low reflectance equivalent signal generators. And it is implemented on K wave band to exactly calibrate the microwave power sensor. Finally the measurement uncertainty sources of the calibration are analyzed and assessed systematically.

Keywords: K wave band power sensor; Transfer standard method; Bias power matching box; Equivalent signal generator
