Australia's over-the-horizon radar technology, once regarded as a costly technological white elephant, is now demonstrating a capability previously considered impossible, a top defence scientist says.

Dr Gordon Frazer, a New Zealand-born researcher with the Defence Science and Technology Organisation, said the next OTHR built in either Australia or the US would be unlike any built before.
"Ir will achieve a performance unimaginable even as recently as five years ago," he said.

Over-the-horizon radar operators by bouncing radio signals off the atmospheric layer, known as the ionosphere, so they follow the earth's curvature.

That allows a far greater range than conventional line-of-sight radar.


Can anyone elaborate ?

Dr Frazer lead a team for an experimental program called HILOW. They demonstrated new radar techniques to enable the OTHR to reject a lot of radar clutter caused by terrain to lower the noise floor of the radar. This means the radar can 'concentrate' on aircraft and ships and hopefully improve sensitivity.

Interestingly the .pdf article referred to in the China threat thread indicates that the Chinese are exploring/building an OTHR to project beyond the second island chain.
From whence has their technology to build this come?
Interesting.

The Soviets were big users of OTH and of course the Chinese could be just doing the same things the Americans, Soviets, Australian and French have done: develop it themselves.
