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...
In many modern radar application, as, for example, Time Modulated Array or High Power Devices [1-3, 5-6], the availability of switches with very low transition time, very low light resistance, very high dark resistance and supporting high powers are required. The objective of this work is to design a photoconductive switch able to generate short pulses with very high amplitude for designing new front-end...
A comparison between two new solution strategies for detecting faulty elements in phased arrays is proposed. The two methods are tested against experimental data. The deterministic approaches assume as input amplitude and phase of near-field distribution and allow to determine the position of the faulty elements. The results confirm the usefulness of the proposed techniques, highlighting the advantages...
A deterministic method for detecting faulty elements in large phased arrays of arbitrary geometry is proposed and tested against experimental data. The approach assumes as data the amplitude and phase near-field distributions and allows to determine both positions and currents of radiating elements. The non-linear inverse problem is properly solved by exploiting a distributional approach, which allows...
