Geometric random channel modeling method for air-to-air communication of unmanned aerial vehicle

The invention discloses a geometric random channel modeling method for air-to-air communication of an unmanned aerial vehicle, and the method comprises the steps: firstly considering the three-dimensional random variable-speed movement of a receiving and transmitting end of the unmanned aerial vehicle, and calculating an effective scattering region, a scattering cluster and a scattering point in a communication system through a communication scene; secondly, introducing a Markov birth and death process to describe disappearance and evolution of the cluster on a time axis; and finally, calculating and analyzing the statistical characteristics of the channel by calculating the impulse response of the complex channel. According to the method, variable-speed arbitrary-track movement of the receiving and transmitting ends of the unmanned aerial vehicle is comprehensively considered, channel change is simulated by using a birth and death process, and angle parameters are generated through random distribution, so th
