Technologies

The Signal Processing Branch is active in a wide variety of advanced technologies used in modern sensor systems.  General competencies of the SPB staff include: The boxes in this figure give one view of the major stages in a radar system from a signal processor’s perspective.  Below each box are sample signal processing technologies used at the corresponding stage of processing.  The five boxes at the bottom represent foundation signal processing technologies that affect the entire radar system design, not just one or two stages.  The GTRI Radar Systems Division’s Signal Processing Branch staff offer expertise and experience in each of these areas.
Progress in signal processing comes from improvements in both algorithms and hardware.  Moore's Law promises steadier, more predictable progress in hardware capability, but algorithmic breakthroughs can provide, overnight, quantum leaps forward equivalent to years of hardware improvement Over the long run, each is about equally important, as argued in this memorandum. The Signal Processing Branch offers expertise in both a wide range of radar and sensor signal processing algorithms and commercial off-the-shelf (COTS), and open standard signal processing hardware technologies.
