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.

Embodiment Construction

[0048] The present invention will be further described below in conjunction with the accompanying drawings.

[0049] The device of the semi-physical simulation of the unmanned aerial vehicle electromagnetic interference communication environment of the present invention is as follows: figure 1 As shown, the system first controls the data link radio frequency signal simulation unit to simulate and transmit the UAV data link radio frequency signal through the master control unit, and the signal enters the channel and interference simulation unit, and uses hardware simulation to generate and superimpose the specific interference of the electromagnetic environment. Unit Control Antenna Rail Control Unit configures the equipment in the microwave anechoic chamber, and then completes the simulation of the UAV electromagnetic interference communication environment. The equipment under test performs demodulation after receiving the output signal, and sends the demodulated signal back to...
