一种基于自校相技术的Ka频段中继用户终端在轨测试技术

A Technique of In-orbit Test for Ka-band Relay User Terminal Based on Phase Self-calibration

随着卫星及各种近地轨道航天器对中继链路数据传输需求的不断提高,各类Ka频段中继用户终端产品得到了大量应用,相应地,Ka频段中继用户终端产品在轨测试方法也得到了关注和重视。论述了一种采用自校相技术的Ka频段中继终端产品的原理,给出了一种Ka频段中继用户终端在轨测试方法。

With continuously increasing need of improving data-relay transmission system involving satellites and varieties of low-earth orbit spacecrafts, various sorts of Ka-band relay user terminal have been widely used. Accordingly, in-orbit test methods for Ka-band relay user terminal are concerned and focused. In this paper, we illustrate the principle of phase self-calibration applied to Ka-band relay user terminal and present a technique of in-orbit test for Ka-band relay user terminal.
