联合战术信息分布系统(JTIDS)是美国研制的一种供三军共同使用的同步时分多址扩频通讯系统,它能在同一射频频道上完成保密数据和话音通讯、精密测距、相对导航以及网内相互识别等功能;特别是该系统具有卓越的抗干扰能力,这是因为采用了混合扩频技术,使敌方干扰机显得无能为力,它比起原频谱间隔需要在整个扩频频谱上耗费好几千倍的功率输出。对此国内已在公开的航空杂志及内部刊物上作过介绍,本文从略。
The Joint Tactical Information Distribution System (JTIDS) is a synchronous time division multiple access spread spectrum communication system jointly developed by the United States and developed by the United States. It can perform secure data and voice communications, precise ranging, relative navigation and network on the same radio frequency channel Especially in the system has excellent anti-jamming capability, which is due to the use of hybrid spread spectrum technology, so that enemy jammers look helpless than the original spectrum interval needs to spread throughout the spectrum to spend good Thousands of times the power output. This has been in the domestic aviation magazines and internal publications made an introduction, this article omitted.
