Abstract:

The proposed effort is aimed at developing a photonic beamformer implementing wavelength-switching for beamsteering of multiple simultaneous-independent RF beams in Receive mode. We propose a novel high-speed, cost-effective and programmable true-time delay (TTD) processor that is shared by all elements of a phased-array antenna (PAA). This technique is based on controlling the optical path of each carrier from a tunable laser operating in C-band. The key innovation is that the direction of incidence of RF beam is determined by the wavelength of the optical carrier through a set of fiber Bragg gratings array that are shared by all T/R elements of the antenna. This method provides high-resolution beamsteering that is immune to EMI. Furthermore, this approach will not require any optical switching technologies removing the need for electronic control of the fiber-optic TTD matrix. However, in order to meet the demand of simultaneous processing of 10 independent RF-beams for PAA with 40,000-400,000 T/R elements it is necessary to supplement this wavelength routing TTD technique with optical CDMA and/or optical dynamic spectrum access technology. The need to operate across wider bandwidth, increased resolution, and higher dynamic range drives the need for simultaneous-independent RF-beams for both Transmit/Receive modes regardless of PAA size.
