The enhanced
transmit/receive and computer-processing technologies of modern radar systems
also are giving rise to imaging radar systems or those that produce
high-resolution pictures from returning signals.
Signal-processing
experts at Mercury are working on a technology called circular synthetic
aperture radar also known as circular SAR, or video SAR. “The processor-intense
part of radar is image formation, which requires significant numbers
crunching,” says Jon Lathrop, market segment director at Mercury.
A specialist
in multiprocessing and other computer-intensive applications, Mercury is
involved in synthetic aperture radar and ground-moving target indication, says
Mercury’s Pool. Circular SAR involves flying a specialized radar system aboard
an aircraft that files around an area of interest, and builds a 3D image based
on successive layers of radar data. “Going to things that are more processor
intensive, such as circular SAR, is where the research is going”.
