校準(zhǔn)六端口反射計的新技術(shù)
A NEW CALIBRATION TECHNIQUE FOR THE SIX-PORT REFLECTOMETER
-
摘要: 作者對Hoer博士(1979)的四標(biāo)準(zhǔn)負(fù)載校準(zhǔn)方法進(jìn)行了改進(jìn),并將該方法與李世鶴博士(1982)的四短路器法結(jié)合使用,提出一種新的六端口反射計校準(zhǔn)方法;它既有李氏法快速、簡單的優(yōu)點,又兼有Hoer法精度高的長處。作為示例,本文給出了新方法在我們研制Ku波段六端口反射計中運用的效果。

Abstract: On the basis of Dr. Hoer s (1979) and Dr. Li s work, a new calibration method for the Six-port reflectometer is proposed. The new method is characterized not only by having the advantage of rapidity and simplicity of Dr. Li s method, but also by having the advantage of high precision of Dr. Hoer s method. An example for applying this method to Ku-band Six-port reflectometer is given. -
