Paper Abstract

The possibilities for using photonic technology to enhance the performance of phased array systems are examined. The principal advantage of photonics is that a photonic array antenna can be partitioned in two halves, the beam-forming manifold consisting of photonic components and the antenna front end consisting of RF components only. The two parts are linked by optical fibers, with the transmitter, receiver, and the beam steering unit conveniently located at a remote site. Several possible architectures of such a system are discussed. It is estimated that, for array applications, a system noise figure of less than 5 dB with a dynamic range of about 60 dB can be achieved with state-of-the-art photonic components and technology.
