SAR imaging technology to match infrared pursued by Raytheon, Nuvotronics, BAE Systems

ARLINGTON, Va.-Synthetic aperture radar (SAR) experts at three U.S. defense companies are developing a new kind of imaging radar technology intended to detect and track moving targets through clouds with the same ability that current infrared targeting systems have in clear weather.

Radar scientists at the U.S. Defense Advanced Research Projects Agency (DARPA) in Arlington, Va., have chosen the Raytheon Co. Missile Systems segment in Tucson, Ariz.; Nuvotronics LLC in Radford, Va.; and the BAE Systems Electronic Systems segment in Merrimack, N.H., for the initial phase of the Video Synthetic Aperture Radar (ViSAR) program.

ViSAR seeks to develop flyable extremely high frequency (EHF) radar exciters and receivers, SAR scene simulation tools, and novel EHF radar-processing algorithms.

Engineers from Raytheon, Nuvotronics, and BAE Systems will develop EHF video synthetic aperture radar technology able to provide high-resolution imagery at high frame rates while minimizing size, weight, and power (SWaP).

DARPA issued the ViSAR solicitation last May, awarded a potential $2 million contract to Raytheon and a $4.2 million contract to Nuvotronics last month, and awarded a potential $1.14 million contract to BAE Systems in November.

DARPA officials already are making plans to move ahead with ViSAR system design and development. The upcoming ViSAR system design and development phase will design a flyable EHF high-power amplifier that will provide sufficient power to enable synthetic aperture radar to produce images through clouds.
