With the development of Unmanned Surface Vehicle(USV)technology,various types of USV have been gradually applied to civil and military fields. As an important part of USV,wireless communication system undertakes the function of information exchange between USV and main control termination. Based on the current development of wireless communication technology,this paper puts forward a wireless communication technology and engineering design method for USV application scenario. In addition,an adaptive wireless communication system is designed,which can provide continuous and stable data chain according to the USV working status. The test results show that the adaptive wireless communication system works well.
