Abstract
We demonstrate hardware auto/cross-correlation measurements of photonically
generated ultrawideband (UWB) RF burst waveforms in the 3–10 GHz range.
Full delay dependent correlation studies with matched waveform pairs reveal
correlation peaks ~15 dB
above those obtained with nonmatching sets of waveforms. The possibility of
real-time correlation detection is also explored, as are correlation measurements
of waveforms that are transmitted over a short line-of-sight wireless link.
With waveforms modified to precompensate for antenna dispersion, 7 dB correlation
contrast between matched and nonmatched waveform pairs is obtained. Our results
suggest hardware correlation detection as a possibility for processing of
arbitrary waveforms in an Ultra-wideband (UWB) receiver.
