Abstract

Real-time acousto-optic signal processors produce data at rates beyond the handling capability of microprocessors. In order to examine the issues associated with detection and post-processing in AO processors, we consider the AO spectrum analyzer. Spatial and temporal data rate reduction techniques are described, so that new energy arrivals only are reported. These techniques are used to overcome spatial signal aberrations associated with the detection process, and temporal aberrations such as modulation or ringing pixels. False alarm rate vs. hardware complexity tradeoffs are examined. Also, a constant false alarm rate probabilistic filter is described.
