Abstract: It first analyzes the channel model of agricultural UAV, and then designs the communication system of agricultural UAV from both software and hardware aspects. Finally, according to the operational characteristics of agricultural UAV, it establishes the simulation platform of agricultural UAV communication system by using statistical modeling method. The simulation results show that the agricultural UAV has large throughput, strong resource allocation ability and network buffer capacity, and high system stability, which can meet the normal communication needs of the agricultural UAV during operation.
