Abstract :
A highly resolved carrier and information extraction of an optically modulated radar signal is presented. The extraction is done by passing the optical beam through a monitoring path that realizes an FIR filter. Replications of the monitoring signal realize the required spectral scan of the filter. Despite the fact that the filter configuration is fixed, each replication experiences different spectral filtering. The radar carrier is detected by observing the energetic fluctuations in a low rate detector. The RF information is extracted by positioning a low rate tunable filter at the detected carrier frequency.
