摘要
在现代航天测控任务中,应答机作为合作测控目标,配合地面测控站完成航天飞行器的测控对应答机技术的研究具有重要意义。为此,介绍了应答机的工作原理,针对应答机的主要性能参数进行了详细的分析和讨论,并展望了应答机的技术发展,对工程应用具有借鉴价值。
In a modem aerospace TT＆C system, the transponder is adopted as cooperative target to implement measuring and controlling of aerospace vehicles along with TT＆C stations, and it is of great importance to study transponder technologies. On this base, this paper introduces the principle of transponder, analyses and discusses some main parameters, and presents technical development of transponder in the future. The study and conclusion is of great benefit to some projects.
