| 摘 要： | 在现有关于六端口反射计校准方法的基础上,结合六端口接收机的特点提出了一种新的校准方法.该方法将经过调制的本地参考信号与本振信号的比值作为校准所需的标准.根据给出的条件来选择调制方式和相应产生标准的状态,将会使校准过程大大简化.采用该方法进行校准,计算量小,无需进行迭代运算,而且广泛适用于各种六端口结的校准.

| Abstract: | Based on existing calibration methods for six-port reflectometers and special features of six-port receivers, a new calibration method was proposed. The method chose the ratio of modulated local referenced signal to local referenced signal as essential standards used for calibration. Modulation modes and corresponding states were selected according to the requirements advanced, and the calibration procedure was sure to be greatly simplified. This calibration method needs no iterative calculations and can be suitable for all kinds of six-port junctions. |
