| Abstract(in English) | National Institute of Information and Communications Technology (NICT) has been currently researching and developing the next-generation communication satellite technology that has flexibly change the coverage using the Digital Beam Former (DBF) and increasing the capacity using the Ka band. Key technology to accurately form the desired beam by the DBF antenna is the systematic error calibration technique of array antenna. To realize the systematic error self-calibration technology, we study the method to measure the systematic error using the coupling characteristics between element antenna of the array antenna and pickup antenna. The periodic ripple was observed in the measured coupling characteristics which was not observed in the analysis result. This is caused by the noise in the measurement environment of an antenna such as reflected wave from the wall of an anechoic chamber. We propose the time domain analysis to identify a reflection position and the gating process to eliminate the effects of reflected waves. This paper shows that the effect of proposed method is confirmed in the combination of array antenna and DBF/channelizer. |
