摘要
借鉴矢量网络分析仪采用标准校正件的方法,提出了一种简单、方便的干涉仪测向低系统误差相位校正方案,通过引入标准功分器作为校准件,来修正校正源通道支路各通道间的不平衡性,最终能够有效消除校正源支路各通道间的固有相差,从而提高系统测向精度。最后,对实现方法进行了定性分析。
According to the vector network analyzer（VNA） calibration method using standard parts, a simple and convenient interfemmeter phase correction method with low system error is proposed. Through the introduction of the standard splitter as a calibration pieces the unbalance among the branch channels of source - channel is corected and eventually the inherent difference among the branch channels can be effectively removed so as to improve the direction find（DF） accuracy. Finally, the implementation method is qualitatively analysed.
