    Abstract:

    Radar videos are characterized by large data volume,high update frequency and large transmission bandwidth.While the data transmission bandwidth of USV (Unmanned Surface Vehicles) to shore is limited,and the transmission information is various and large in volume.In the use of USV,radar videos are indispensable support for shore-based operators to ensure safe navigation,quick search and accurate confirmation of belligerent objects.However,there is an inevitable contradiction between the shortage of bandwidth resources of shore-USV data intercommunication and the large information transmission demand of radar videos.Based on the principle of radar detection and imaging,this paper presents the digital representation of the radar videos,and realizes the restoration and display of radar video by the shore-based control station through video compression,data transmission and restoration display.The proposed wireless transmission method is applied to a USV control system,and results demonstrate that it is high in video compression ratio,low in processing delay,with complete video restoration and good fault tolerance.
