| 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.

| Abstract: | According to the vector network analyzer(VNA) calibration method using standard parts, a simple and convenient interferometer 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 corrected 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. |
