The following article is a summary using my own words. The original
article can be found in the newspaper Western Australian (Feb. 25, 1991).
The title of the original article is "Our Radar is the World's Best".

>>OTHR beats the Stealth!!!<<
Auatralian engineer from Defence Science and Technology Organisation (DSTO)
have created an early-warning system capable of tracking even the US Stealth
bomber with a sophisticated computer system. They claimed Jindalee will be
the best and most advanced early-warning surveillance system in the world.
Late in 1989, Australian scientists working on the project said it
could detect America's new $700-million Stealth bomber. A US Air
Force spokesman immediately described the claim as "hogwash".
But One independence source (Earth2000, Western Australian) has confirmed
that the Stealth technology - Relying on absorbant paint and sharp angles
to deflect radar signals - can be beaten by OTHR because the radar system
looks down on a target instead of straight as it like traditional radar
systems.
Another independent sources (Far Eastern Economic Review) did confirm
that experiments at a US OTHR station had detected both the Stealth
bomber and Cruise missile.
The OTHR system is intended to see over the horizon by bouncing a
signal off the ionosphere. The signal is then bounced back from an
aircraft to a radar receiveer where it is read with the help of a
computer.
According the scientists involved in the project, there are still
some minor problems, such as Jindalee system could pinpoint the
position of an intruder down to only a box of 50 km or so square
of indefinite height.
They also said that if Jindalee could only guide an fighter pilot to
the general vicinity of an enemy plane, he might then have to turn on
his own search radar - make himself a target to the enemy.
But Jindalee project director Bob de Boer said the radar is now functioning
well. Prsumablely they have solved or at least partially solved those awkward
problems.
