•The radar system, known as the Jindalee Operational Radar Network (JORN) derivative, is being adapted for the harsh Arctic environment to monitor increased Russian and Chinese aerial activity in the North.
•The A$2.5 billion contract includes a significant technology transfer agreement, requiring Australian engineers to collaborate with Canadian firms to 'harden' the radar against extreme sub-zero temperatures and ionospheric disturbances unique to the polar region.
•This export marks a strategic shift in the AUKUS partnership framework, expanding defense cooperation beyond submarine technology into advanced surveillance and intelligence-sharing infrastructure.
•The deal is expected to create a joint 'Arctic Surveillance Corridor,' allowing both nations to share real-time data on hypersonic missile threats that utilize low-altitude flight paths.
•The Canadian Department of National Defence (DND) plans to integrate this radar with its existing North Warning System (NWS) to replace aging sensors with modernized Over-the-Horizon (OTH) capabilities.

Utilizes High Frequency (HF) skywave propagation to bounce radar signals off the ionosphere to detect targets beyond the line of sight.
Employs advanced digital beamforming and adaptive clutter rejection algorithms to filter out auroral interference common in Arctic latitudes.
Features a distributed transmitter-receiver architecture to minimize the impact of localized jamming or environmental signal degradation.
Incorporates AI-driven signal processing to distinguish between atmospheric noise and low-observable (stealth) aerial threats.

Canada will achieve full operational capability of the Arctic radar network by 2029.

The integration timeline aligns with Canada's broader NORAD modernization commitments and the scheduled decommissioning of legacy radar sites.

Australia will establish a permanent Arctic-focused defense research office in Ottawa.

The complexity of the technology transfer and the need for ongoing environmental calibration necessitates a long-term, on-site technical presence.
