Riassunto
Il concetto di Software Defined Radio (SDR) nasce negli anni ’90 quale risposta a molteplici esigenze, tese a semplificare la logistica di procurement e di gestione, ad aumentare la flessibilità di utilizzo degli apparati e a disporre di possibilità evolutive sempre più spinte. Il concetto base è quello di trasformare un tradizionale apparato TLC in una piattaforma hardware semplificata abile a supportare molteplici servizi, da “riprogrammare” a seconda del tipo di utilizzo tramite software: la radio diventa di fatto una sorta di “computer con l’antenna”. Lo scenario futuro è un’evoluzione del concetto di SDR a favore di tecnologie quali la Cognitive Radio e la Intelligent Radio, in grado di effettuare in autonomia alcune funzioni che oggi necessitavano di personale addetto; questa evoluzione si può conseguire attraverso lo sviluppo di algoritmi software a capacità molto avanzate di machine learning. Ciò permette ad esempio di poter adattare i sistemi radio alla situazione delle emissioni elettromagnetiche presenti nell’ambiente circostante, che è analizzata e confrontata con i parametri degli apparati al fine di stabilire una comunicazione rapida, sicura ed affidabile tra gli assetti cooperanti. Questi concetti sono in via di consolidamento per lo sviluppo dei sistemi di telecomunicazione militare di prossima generazione, in alcuni casi già presenti in vari settori tecnologici come in quelli relativi all’intelligenza artificiale, con lo scopo di poter ampliare la disponibilità di servizi di interconnessione e fronteggiare varie situazioni operative, sempre più complesse.
The concept of Software Defined Radio (SDR) was born in the 90s as a response to multiple needs, aimed at simplifying the logistics of procurement and management, to increase the flexibility of use of the equipment and to have evolutionary possibilities increasingly pushed. The basic concept is to transform a traditional TLC apparatus in a simplified hardware platform able to support multiple services, to "reprogram" depending on the type of use by software: the radio actually becomes a kind of "computer with the antenna". The future scenario is an evolution of the SDR concept in favor of technologies such as Cognitive Radio and Intelligent Radio, able to carry out in autonomy some functions that today needed staff; this evolution can be achieved through the development of software algorithms with very advanced machine learning capabilities. This allows for example to adapt radio systems to the situation of electromagnetic emissions in the surrounding environment, which is analysed and compared with equipment parameters in order to establish rapid communication, safe and reliable between cooperating structures. These concepts are being consolidated for the development of next generation military telecommunications systems, in some cases already present in various technological sectors such as those related to artificial intelligence, with the aim of being able to expand the availability of interconnection services and cope with various operating situations, increasingly complex.
