Originally, Military Standard 188 (MIL-STD-188) covered technical standards for tactical and long haul communications, but late
7、r evolved through revisions (MIL-STD-188AY MIL-STD-188B) into a document applicable to tactical communications only (MIL-STD-188C). 2. The Defense Communications Agency (DCA) published DCA Circulars (DCAC) promulgating standards and engineering criteria applicable to. the long haul Defense Communica
8、tions System (DCS) and to the technical support of the National Military Command System (NMCS). 3. As a result of a Joint Chiefs of Staff (JCS) action, standards for all military communications are now being published in a MIL-STD-188 series of documents. The MIL-STD-188 series is subdivided into a
9、MIL-STD- 188-100 series covering common standards for tactical and long haul communications, a MIL-STD-188-200 series covering standards for tactical communications only, and a MIL-STD-188-300 series covering standards for long haul communications only. Emphasis is being placed on developing common
10、standards for tactical and long haul communications published in the MIL-STD-188-100 series. 4. This document contains technical standards and design objectives for tactical single channel VHF radio equipment. It supersedes paragraph 4.5.8 of MIL-STD-188C applying to tactical single channel VHF radi

The purpose of this document is to promulgate technical design and engineering parameters in the form of mandatory system standards and optional design objectives that are considered necessary to ensure inter
33、operability and to-promote compatibility and commonality among tactical single channel very high frequency (VHF) radio equipment. It is also the purpose of this document to establish a level of performance of tactical single channel VHF radio equipment considered necessary to satisfy the requirement
34、s of a majority of users. The technical parameters promu1 gated by this document represent, in general , minimum interoperabi 1 ity and performance characteristics which may be exceeded in order to satisfy specific requirements. For example, other signal levels may be added to the minimum mandatory
35、interoperabil ity characteristics as stated in the note of 5.1.3.7. Standards contained i.n this document have been based on measured per- formance of existing VHF radio equipment according to the definition of system standards as stated in Federal Standard (FED-STD) 1037. Conse- quently, it is not
36、the purpose of this document to establish all standards considered necessary to ensure interoperability of future VHF radio equip- ment that is currently being designed and developed. However, this docu- ment provides guidance to the designers of future VHF radio equipment by standardizing the techn
37、ical characteristics of existing VHF radio equip- ment to .facilitate the necessary design decision required to achieve interoperability between existing and future VHF radio equipment. It is not the purpose of this document to serve as a stand-alone, comprehensive reference containing all technical
38、 parameters and other specifications. Therefore, parameters for such items as size and weight limitations, connectors, cable assemblies, or power supplies are not con- tained in this document. These parameters and other design details have to be established, based on specific requirements, and have
39、to be care- ful ly tailored in accordance with the pol icies of DoD Directive (DoDD) 4120.21. 7 details required for the design of new equipment or the preparation of This document is not intended to be an engineering textbook or a reference handbook for VHF radio equipment. It is assumed that users
40、 of this document have a basic technical background in the design and engineering of VHF radio equipment. This document also is not intended to inhibit advances in communictions techno1,ogy. Such advances are encouraged by including designobjectives which should be achieved if economically feasible.
41、 Additionally, such advances are facilitated by standardizing upper or lower 1 imi ts rather than fixed parameters values and by not specifying the technology that should be used in the design and development of VHF radio equipment to meet the required standards. 1 Copyright Communications - Electro
