Abstract

A microwave photonic true time delay line based on an integrated Kerr comb source with 49 GHz free spectral range was proposed and demonstrated. We theoretically analyze the performance of a phased array antenna and show that this large channel count results in a high angular resolution and wide beam-steering tunable range.
