| 抄録 | （和） | Aircraft radio altimeters (RAs) are essential avionic devices for measuring aircraft altitude. Aircraft RAs operate between 4.2−4.4 GHz. However, Sub-6 5G mobile systems have been introduced in adjacent radio altimeter bands. In Japan, the radio altimeter frequency band and guard band for 5G mobile systems are both 100 MHz, which is narrower than those in other countries. Thus, under Japan’s narrow guard band conditions, the risk of interference is higher than in other countries such as the United States and France. In this study, the electromagnetic interference (EMI) issues of aircraft RAs due to Sub-6 band 5G mobile communications systems under Japanese conditions are discussed. First, EMI susceptibility evaluations of aircraft RAs under Japanese Sub-6 band 5G mobile systems are discussed. Twelve RAs for large fixed-wing aircraft and eight RAs for small- and medium-fixed-wing aircraft and helicopters are measured. The study subsequently discusses the development of the EMI occurrence condition analysis method, based on the measured EMI susceptibility characteristics of RAs, the characteristics of Sub-6 band 5G mobile base stations, and a three-dimensional airport model. |
