UAV relay communication is widely used in modern warfare. However, the relay transmission mode currently used has the disadvantages of low network throughput, large information transmission delay and easy eavesdropping of information. As a new transmission technology, physical layer network coding can improve the throughput of relay network, reduce the delay of information transmission and has broad application prospect in UAV relay communication. The application scenario of UAV relay communication is introduced. The basic principles and advantages of physical layer network coding are expounded. The application prospect of physical layer network coding in UAV relay communication is prospected. The application prospect of UAV relay communication is analyzed. The problem
