Abstract
Disclosed are an airborne electromagnetic wave device, and an anti-interference system, method and apparatus. The anti-interference method comprises: detecting an interference source, and obtaining a working frequency and a bandwidth of the interference source; calculating an interfered bandwidth range at least on the basis of the working frequency and bandwidth of the interference source; and controlling an electrically tunable filter provided in a transmission channel of the airborne electromagnetic wave device to filter signals within the interfered bandwidth range. Hence, the interfered airborne electromagnetic wave device is triggered to control the electrically tunable filter to filter the signals within the interfered bandwidth range, so that the interfered airborne electromagnetic wave device suspends signal transmission within the interfered bandwidth range, so that communication interference among different satellite communication systems is eliminated; moreover, the electrically tunable filter is provided on the transmission channel of the interfered airborne electromagnetic wave device, so that the present invention can be widely applied to multiple different airborne e…
