AI Technical Summary

Problems solved by technology

However, the communication environment of the UAV data link is often very complex. During the propagation of radio waves, not only will it be affected by factors such as surrounding terrain, weather, and aircraft attitude, but it will also face various forms of even high-power human interference.

Under the combined action of complex electromagnetic environment and interference, the transmission performance of the UAV data link will drop sharply, and even cause the entire system to be paralyzed in severe cases.
