This report is a final report of the activity Analysis of Flexible Microwave Systems within the project MIRA - Array Antennas and Programmable Microwave Systems. The system analysis is intended to review the prerequisites to integrate multiple RF-functions into a single flexible multifunction microwave system. The system analysis has been performed with typical requirements for international operations. In the project we focus on surveillance and communication functions. The system analysis forms a basis for the studies of concepts and technological solutions for systems, RF-electronics and conformal antennas for flexible microwave systems. A number of system concepts for surveillance functions have been proposed.
