Classification: CPC H | IPC H

Claim 6:
7. An airborne electromagnetic wave device comprising a baseband processor and an electrically tunable filter connected to the baseband processor, wherein
the electrically tunable filter is arranged on a transmission channel of the airborne electromagnetic wave device; and
the baseband processor is configured to control, in response to receiving an interfered band, the electrically tunable filter to increase attenuation of signals within the interfered band by a preset value, wherein the interfered band is calculated by determining a sum of an operating frequency of an interference source and a first bandwidth as an upper limit, and determining a difference between the operating frequency and the first bandwidth as a lower limit, to acquire the interfered band, wherein the first bandwidth is a sum of a bandwidth of the interference source and a preset transition protection bandwidth.
