Drones are expected to be used in industrial applications. Within the small fuselage of a drone, various electronic modules and antennas for wireless communication are placed in close proximity. Radiated noise from the electronic modules can interfere with radio communications and cause the drone to malfunction. Drones are configured to perform various actions, and the characteristics of the radiated noise vary depending on the state of the action. In this research, we focused on the ever-changing action states of drones. Radiated noise was analyzed and evaluated in order to clarify the extent to which radiated noise in various behavioral states, such as the ascent state and the video recording state, affects wireless communications. We analyzed the effects of behavioral changes in the 10 MHz bandwidth of the LTE (long term evolution) communication band used in drone operations. The results showed that the radiated noise of drones is not always constant, but varies from a few dB to dozens of dB within a few milliseconds, with the most significant changes about 30 dB. This suggested that electromagnetic interference occurs when the radiated noise becomes stronger. The effect of radiated noise on LTE communication was also confirmed using an LTE communication simulator. Analysis of changes in the drone's behavioral state is expected to lead to clarification of the mechanism of radiated noise generation and contribute to appropriate electromagnetic interference countermeasures. |
