Unmanned aerial vehicle channel modeling method based on antenna radiation pattern

The embodiment of the invention provides an unmanned aerial vehicle channel modeling method based on an antenna radiation pattern. The method comprises the following steps: initializing unmanned aerial vehicle channel model parameters under a cellular network; simulating a directional diagram of a base station antenna of the cellular network by using a rectangular grid array planar array; and calculating an antenna pattern, an impact response and a transfer function from a transmitting antenna to a receiving antenna by adjusting a beam direction based on the rectangular grid array planar array. According to the unmanned aerial vehicle channel modeling method based on the antenna radiation pattern provided by the embodiment of the invention, the rectangular antenna array is used for simulating the pattern of the base station antenna, and the beam direction is adjusted to reduce the signal interference and enhance the network coverage range, so that the method accords with an actual unmanned aerial vehicle comm
