前言战术防卫通信系统(如松鸡系统)与民用系统有很大区别。这不仅是在设备工程方面(如坚固性和运转可靠性),而且还有电信工程方面的差别。其结果是,在假设和推论电信性能标准时,需要采用不同的方法。它们与民用系统的标准相似,但需作重大修正。本文的目的不在于提出普遍适用于防卫通信系统的性能标准。然而,通过介绍松鸡系统采用的方案可以解决遇到的某些问题。表1中归纳了民用系统与战术防卫通信系统之间的主 Preface Tactical defense communication systems (such as grouse system) and civil systems are very different. This is not only in terms of equipment engineering (such as ruggedness and operational reliability), but also in terms of telecommunications engineering. As a result, different approaches need to be taken when assumptions and corollaries on telecommunication performance standards. They are similar to civil system standards but require major revisions. The purpose of this article is not to propose performance standards that are universally applicable to defense communications systems. However, some of the problems encountered can be solved by introducing the scheme adopted by the grouse system. Table 1 summarizes the civil and tactical defense communications between the main system
