A Deployable Synthetic Aperture Radar Antenna with Multiple Phase Centres for Monitoring Arctic Snow and Sea Ice — The Arctic is rapidly exhibiting signs of global climate change. The transition from thick
perennial sea ice to a seasonally ice-free Arctic Ocean has major consequences for sustainable
development, transportation, and communities in Arctic regions. Knowledge of the physical and thermodynamic state of sea ice is therefore critically important in understanding how climate change is affecting the planet.

This project will develop advanced deployable antennas that can be used in satellite remote sensing applications, with the goal of improving Canada’s capacity for monitoring the Arctic. The proposed antenna concepts have never been used in space applications and must be further developed for use on future missions. The designs are a technological leap since the concept allows one antenna to perform as if there were two antennas on the satellite and provides equivalent satellite imaging capability. This means that upcoming satellites will have lower mass and will be more compact, which a
