The need for constant improvement of radio communications arises from the growing need for voice and data transmission with high survivability and bandwidth of channels in radio links, providing information exchange between military command and control bodies, units, weapons systems and individual military personnel.The radio stations can operate both at a fixed frequency and in the frequency-hopping spread spectrum (FHSS). In the absence of organized radio interference, the mode of operation of the radio link at a fixed frequency is established. When using electronic suppression (ES) by the enemy, as well as in a complex jamming environment, the main means of protection against suppression of the communication FHSS.The technical implementation of the FHSS mode is a rather complex and costly process, so its choice can be due only to the increased requirements for noise protection. In addition, FHSS systems do not allow high data rates to be achieved due to a number of difficulties associated with coherent frequency synthesizers.The effectiveness of radio communication systems (RCS) is determined by many factors of different nature, it can be conditionally divided into three groups: the quality of the RCS, the conditions for the operation of the SRZ, the ways of using (using) the RCS.The characteristic features of the creation, deployment and operation of radio communication systems at the tactical level of control are a high degree of uncertainty in the characteristics of their functioning in the dynamics of an armed conflict, which necessitates constant improvement of approaches to justifying the choice of directions for the development of RCS.Analysis of noise protection measures by introducing FHSS mode into the radio station dictates the need for rational choice of time characteristics of the process of analog-to-digital conversion of signals (speech and data) and the process of packing the converted information into packets with pauses needed to adjust the operating frequency.The article reflects the views of the authors and proposes proposals for the approach to justify the effectiveness of RCS with FHSS on a generalized indicator of the probability of timely and reliable delivery of messages (services), which will set requirements for the criteria of technical characteristics of RCS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
