摘要
阐述了What if软件与传统软件相比做频率规划的优点;以S频段测控系统下行链路为例给出了频率规划的方法和步骤;在此基础上给出了可变中频配置方案解决多目标同时测控中可能产生的交调干扰,最后指出了合理的频率规划对提高群时延指标的重要性。
Merits of using software What if for frequency plan compared with traditional approaches are presented. Taking S-band TT＆amp;C system downlink as an example to provide the methods and procedures for frequency plan. On this basis,a tunable intermediate frequency allocation plan is proposed to deal with cross modulation interference in multiple targets TT＆amp;C. Finally the importance of reasonable frequency plan for increasing group delay index is pointed out.
