Abstract
A method and apparatus for generating an arbitrary UWB waveform are presented. An optical comb generator generates a serial stream of optical tones and an optical beating tone. A serial-to-parallel converter receives the serial tones and converts them into parallel optical tones. A spatial light modulator receives the parallel optical tones, and independently adjusts at least one of the phase and amplitude of each to generate the components of an arbitrary waveform. Next, each one of a plurality of optical-to-electrical converters receives a parallel optical tone and the selected optical beating tone, which are beat with the optical beating tone, producing electrical notes, representing differences between each parallel optical tones and the optical beating tone. Each antenna element is connected to receive an electrical note and to launch a signal based thereon, such that the launched signals are superimposed to the arbitrary waveform signal.
