Communications and Networks

Military satellites are critical sources of communications and data for today’s operations environments. Through DARPA’s Phoenix program, useable antennas or solar arrays from retired satellites in geosynchronous orbit (GEO – 36,000 kilometers above earth) could be removed and potentially repurposed as components for new satellites to provide vital mission support.

Dr. Karr joined DARPA as a Program Manager in June 2012. His areas of interest include ISR and EW technologies and systems, optical LPD/LPI sensing and communication, new weapon technologies and effects, weapon and ISR countermeasures and counter-countermeasures, space control, and the integration of space with tactical systems.
