Technical Field
The utility model relates to a cross medium aircraft's communication technology field. More specifically, the present invention relates to a low frequency conduction system for a cross-media aircraft.
Background
When the cross-medium aircraft works on the water surface, various radio communication modes can be utilized. However, when the underwater vehicle works underwater, most of radio waves are reflected back to the air by the water body and hardly penetrate through the water surface, most of the radio waves are absorbed by the water after entering the water, and therefore the machine body cannot be in contact with the outside by using the radio device. The attenuation effect of the water medium on radio waves is far greater than that of air, and the seawater has stronger electric conductivity than water, so that the attenuation of the radio waves is further enhanced. Research shows that the shorter the wavelength of radio waves, the easier the radio waves are reflected or absorbed by water, and the poorer the penetration capability is. The control signals of the traditional unmanned aerial vehicle are basically 2.4G high-frequency signals, and the underwater attenuation seriously influences the control performance. The ground station is located in the air, and when the aircraft is underwater, most of signals transmitted to the ground by the aircraft are absorbed by water, and most of signals transmitted to the aircraft by the ground station are reflected by the water.
