无人机无线图传通信传输解决方案

发布时间:2019/05/20

          近几年,民用无人机技术发展迅速,无人机不再是军队专属装备,众多无人机厂家的技术保障,使得公司与个人以及各种项目开发中使用无人机成为可能,那么问题来了,军用无人机拥有超清晰的分辨率,与卫星对接的高宽带高流量传输的速率,以适应精确打击的必要;民用无人机则主要用于大地测量、遥感等,主要目的是获得高分辨率、能描述物体集合形态的二位或三维图像,但是高分辨率图像数据量相当大,而且随着地面分辨率提高,需要传输的图像数据量呈几何级数增长,数据码数率也迅速增长,因此,图像的高速传输已经成为制约无人机应用的重要问题。

  鹏鑫威科技通过自行研发成产而成的无人机无线视频通信传输系统,该系统采用先进的COFDM(信道编码的正交频分复用)全数字调制解调技术及MPEG2/MPEG4数字压缩编码技术,其多载波等技术特点,抗多径能力强,具备“非视距”、“绕射”传输特点和良好穿透能力,能够满足无人机无线通信任务。

  客户需求:采用COFDM调制方式功率控制在500mw-1w、距离能够满足3km 整机重量不超过500g、输出接口采用AV / BNC 频率选定在公安频率(336-344MHz)并可宽限到300-800MHz,带宽可调 视频压缩格式为H.264或MPEG-2/4 支持高速移动,移动速度>70km/h 延时< 200ms
