| Abstract(in English) | In device such as a drone that has a build-in 5G (5th generation mobile communications) mobile terminal for controlling itself, electromagnetic noises generated by the device itself may cause electromagnetic interference to radio waves for the communications and control. This is the so-called a problem of intra system electromagnetic compatibility (EMC). On the other hand, when a measuring electromagnetic noise with an antenna, not only electromagnetic noise that interferes with the communications, but also electromagnetic fields that contains all waveform components are measured inescapably. In this paper, we focused on a technology of the independent component analysis (ICA), which has been used to separate and extract specific waveforms from mixed signals, for example, brain waves or acoustic waves. Applying the ICA to the extraction of electromagnetic waves, it was examined whether a specific electromagnetic noise component could be extracted from the waveform observed by antennas. In this study, the result of extracting electromagnetic waveforms by using ICA from a mixture of multiple signals assuming the electromagnetic noise generated by a drone and radio waves from mobile terminals installed in the drone itself was shown. From the result, we also confirmed the applicability of the ICA to a problem of the intra system EMC. |
