    摘要:

    雷达视频数据量大，更新频率高，传输带宽占用量大.无人艇（USV）岸艇数据传输带宽有限，传输信息种类多、数量大.在无人艇使用过程中，雷达视频是岸基操作人员安全航行保障、交战对象搜索确认等不可或缺的支持信息，然而岸艇数据互通带宽资源的紧缺和雷达视频的大信息传输需求之间的矛盾必然存在.本文根据雷达探测成像原理，对雷达视频进行数字化表示，经压缩、数据传输和复原显示，实现无人艇岸基控制站对艇载雷达视频的还原显示.该技术在某型USV控制系统中的应用结果表明：视频压缩比高、处理时延低、视频还原完整、容错性好.

    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.
