Finnish software radio programme and demonstrator

This article describes the developments in the field of emerging new military radio systems to be deployed in Finland. This paper describes the evolution path toward Finnish software radio. The Finnish software radio programme has been divided into several phases to manage research and development risks and currently the program is in its demonstrator phase Finnish software radio demonstrator programme (FSDR). The demonstrator platform, that is being build, is a software defined radio wherein the developed wideband applications can be demonstrated. The emphasis of this paper is on the demonstrator structure and the philosophy used therein. The systems deployed on the demonstrator platform - tactical radio communication system (TRCS) and national tactical positioning system (NTPS) - are also introduced. Brief introduction of the adaptive antenna system (AAS) to be applied in the demonstrator is given.
