Australia secures $2.5 billion over-the-horizon radar export deal with Canada
By
Christopher McFadden
Summary
Australia has secured a $2.5 billion export deal with Canada to supply over-the-horizon radar (OTHR) technology, similar to the JORN system, through BAE Systems. The radar uses the Earth's ionosphere to bounce radio waves and detect threats like aircraft or cruise missiles from thousands of miles away, addressing the challenge of detecting threats over the Arctic region where conventional radar has limited range and reaction time.

· 3 pulledFor example, potential rival nations like Russia could, in theory, launch aircraft or cruise missiles from thousands of miles away over the Arctic.
By the time a normal radar sees them, they're already pretty close, reducing reaction times to respond.
This clever piece of tech is able to bounce radio waves off the Earth's ionosphere to greatly extend range beyond the horizon.
