摘要:

讨论了群时延的概念及群时延的测试原理和方法,并在通信卫星在轨测试的工程实现中,针对卫星转发器频段多及Ka频段转发器频率较高的特点,重点描述了综合群时延测试的方案设计及实现。经工程验证,该方法提高了在轨测试的效率和群时延测试精度。

Abstract:

This paper discusses the concepti of Group Delay(GD),and analyses the principle and method of GD measurement in detail.It gives a design method for measuring the GD in IOT(In Orbit Test) for multi-band payload including Ka-band of the satellite communication in practical application.Practical measurement proves that the method improves the IOT efficiency and GD test accuracy.

Key words: communication satellite,transponder,group delay(GD)characteristics,in orbit test(IOT),microwave system analyzer (MSA)
