当前通信、导航、识别(CNI)功能存在着诸如饱和、天线和设备数目众多、使用缺陷等各种问题,需要通过设备综合化,而不是从单个设备的发展来寻求对策。本文分析了不同程度的综合化,最后介绍可达到最完善综合化的时/频系统,叙述了时/频系统实现每一 CNI 功能的原理,并从经济角度,通过对机载设备相对成本的比较,分析了用综合化时/频系统(包括或不包括着陆和防撞功能)来取代分立设备的可能性。
Currently, CNI functions have various problems such as saturation, large number of antennas and devices, defects in use, and the like, and the countermeasure needs to be sought through device integration instead of individual device development. This paper analyzes the different degrees of integration, and finally introduces the most complete integration of the time / frequency system, describes the time / frequency system to achieve the principle of each CNI function, and from an economic point of view, the relative cost of airborne equipment In comparison, the possibility of replacing discrete devices with integrated time / frequency systems (with or without landing and collision avoidance functions) was analyzed.
