摘要
针对目前飞行试验视频遥测传输中遇到的遥测频带资源有限、传输视频路数少、数据保密性差等技术问题进行了分析，提出利用单向无线网络进行数字视频遥测传输的技术优势，分析飞行试验单向无线网络数据传输中网络通信协议，主张采用H．264视频压缩技术进行飞行试验图像数据遥测传输的优势技术，对在无线环境下视频传输需要解决的压缩数据编码问题，采用分级编码技术和误码掩盖技术；结合飞行试验对研究结果进行了技术验证，对试验方法和结果进行了说明。
In this paper, the problems of telemetry transmission in flight test were analyzed. A new Unilateral wireless network was presented by which to solve the problems of air-ground multiple digital video transmission. The H.264 video compression principle was applied, with the code scale, and the results of flight test were proved. The methods and results of verification were illustrated as well. At the end of this paper, the expectation on this new technology was expressed.
