In recent years, space-based radar technology has undergone significant advancements, enhancing our ability to monitor and protect Earth's orbit. A notable development is the Deep Space Advanced Radar Capability (DARC), a trilateral partnership between the United States, the United Kingdom, and Australia. DARC aims to establish an all-weather, global system to track very small objects in geosynchronous orbit, safeguarding critical satellites. The first of three planned radar sites in Western Australia was completed in December 2024, marking a substantial milestone in space situational awareness. spaceforce.mil
Simultaneously, private companies are contributing to this technological evolution. Seattle-based startup Kapta Space has secured $5 million in seed funding to develop metasurface antenna technology for space-based radar systems. This innovation promises smaller, lighter, and more energy-efficient antennas, potentially reducing launch costs and enhancing satellite performance. Additionally, Finnish satellite operator ICEYE has partnered with Saab to integrate advanced space-based radar data into military command systems, aiming to improve tactical decision-making and situational awareness. farmonaut.com, armyrecognition.com
