NARMA: New radar architectures for air traffic management and metereology

This paper describes the results of a research project which is aimed at designing and realizing innovative multifunctional radar architecture based on Tile elements. In this paper we focus on the description of the design strategy of the antenna front end and on the digital beamforming architecture able to meet the performance requirements. In particular a suitable digital beamforming technique exploiting overlapped subarrays is introduced and obtained results are presented.
