Ultra-wideband multi-beam forming of the synthesized RF system based on true-time-delay technique

Synthesized RF system is the development direction of complex electronic system platform in the future, and the implementation of synthesized RF system is the key technology. This paper focuses on the multi-beam forming technology of UWB synthesized RF system. The cost of hardware implementation based on the traditional TTD (true-time-delayer) beam-forming technology is high and the scanning angle range is limited. In this paper, we firstly address a multi beam-forming approach based on true time delayers (TTD). Then we build a lens-based array system which can form high gain beams with a small number of antenna elements and also establish the mathematical model of the lens. Lastly, we proposed a radiation pattern synthesis method to scan continuously and radiate multi-beams of different function signals simultaneously. Simulation results verify the effectiveness of the proposed implementation and scanning method.
