Performance of an optically fed conformal array

Abstract

The authors present an overview of the development work of a wideband photonic array antenna. They focus on the performance of a unique L-band (850-1400 MHz) 24/spl times/4 element conformal array, supported by a true-time-delay beamforming network. A 2-ns pulse was injected into the system and the round trip impulse response was measured to demonstrate the array's 550 MHz (50%) instantaneous bandwidth.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
