| Abstract: |
| According to the vector network analyzer(VNA) calibration method using standard
part
s, a simple and convenient interferometer phase correction method with low syst
em error is proposed.Through the introduction of the standard
splitter as a calibration pieces the unbalance among the branch channels of s
ource-channel is corrected and eventually the inherent difference among the bran
ch channels
can be effectively removed so as to improve the direction find(DF) accuracy.Fi
nally,the implementation
method is qualitatively analysed. |
