摘要
针对航空武器试验过程中视频遥测能力不足的现状,采用了多路数字视频时域复用方法,实现了单频点PCM通道传输多路机载视频的功能。将不同格式和来源的机载视频进行采集、压缩,压缩后的数据经过二次编码、合流,使其符合IRIG 106规范后使用PCM通道遥测下传。
According to the lack of abilities of video telemetry in airborne weapon test process,the multi-channel airborne digital videos transmission is realized by PCM encoder at single frequency point,adopting time domain reuse in multiple digital video.Airborne images from different formats and sources are gathered and compressed,and the compressed data,which has been encoded and interflowed twice to adjust to the IRIG 106 standard,are transferred to ground through PCM channel.
