Multiple reflection signals between the probe and the antenna is always ignored in frequency domain near field measurement, which can be reduced by technique such as time gate in the time domain near field measurement sometimes. There are few articles to study about influence of the multiple reflection error affecting the result of the test for it is difficult to determine multiple reflection signals...
Time domain near field measurement theory was first present in the 1994, since then practical test verified the feasibility of the measurement technology. However, error system of time domain near field measurement has not been summarized as system in frequency domain measurement which makes time domain measurement can not be applied in engineering tests as frequency domain measurement. In this paper,...
The correction in frequency domain is different and constant in each frequency point, because of multi-reflection, waveguide transmission, coaxial conversion factors and many other factors. This article focuses on the system, explores the relationship between the parts that include the reflection, transmission attenuation, waveguide coaxial switch matching and probe receiving features and frequency,...
At present, a complete measurement system has been built up successfully by our laboratory, besides its engineering implement has been accomplished also. We can show an antenna's radiation field in a form of 3D animation dynamically with this measurement system, which demonstrates the time-domain near-field measurement theory and the time-domain near-field measurement system are practical. The present...
