中文摘要:
      提出了一种新的六端口自校准方法.本方法从六端口相对功率理论出发,导出了六端口系统常数的自校准方程,给出了求解系统常数初值的方法,并利用梯度法对方程组求解,仿真结果表明用一个匹配负载、四个失配负载就可以解出系统常数.
英文摘要:
A new calibration method of the six-port measurement system is proposed.The self-calibration equation of the six-port reflectometer is derived from the six-port relative power theory.A new method of finding initial estimation needed for the iteractive method is discussed.The system equations are solved by the grads method.The simulation result shows that a matched load and four unmatched loads are needed for the self-calibration.
