'Australia is using a sophisticated new radar network that can detect stealth bombers, curb illegal immigration and spy on neighbouring nations
from at least 3000 kilometres away. The $A1.8 billion Jindalee Operational Radar Network (JORN) has taken more than 30 years to complete but is now
undergoing final trials.
JORN is designed to monitor air and sea movements across 37,000km of largely unprotected coastline and 9 million square kilometres of ocean. It is
being used to cast a security shield across Australia's remote northern approaches without the high cost of maintaining constant maritime and air
patrols.'
The rest ....

Radar 2 (blue arc) is located at Laverton
IRSU (pink arc) is the Jindalee Alice Springs Facility
Radar 1 (yellow arc) is located at Longreach

As far as I know only The US, Russia and China deploy these types of radar.

I have read somewhere that the Jindalee radar can even see into mainland China. I can't seem to find any reports of this I will keep looking.

Thk u so such for reminding me of JORN's pic. I'm not sure that the scanning range of JORN can cover the Soutn sea of China unless you can offer me
the specific sample of its capability.
By the way, judging from what you say, I'm quite doubt on your nationality.

Obviously OTH has the capacity to cover a vast area, but it doesn't make sense that China shall make a big worry about it, afterall China faces a
containment policy by USA led westen society from long time ago.
What I'm worried about is USA becoming more and more aggressive than ever, and that is the key to my opinion.

Well we have to be able to detect the nuclear missiles coming in if we are to be part of the defense shield 
Also we in Australia had a big political thing on immigration a couple years ago.. We're sick of these boat people.

That radar system is cool. I did not know that the Australians were investing in military technology like that. I want to know what else they are
coming out with.

Well the US will give us nukes in an emergency.
We should be able to build our own nukes in 2 years time.
We're one of those countries that are able to have nukes, have the capabilities to do so, but dont.

No I g all tese other nations will be trying to build a cloaking device of some kind to keep them Australians out of their own territory. Or at least
that's wht they do In Command and Conquer.

The australians have recently made major improvemants to their military but I did not know about this. Mind you if it is anything like the Colins
class sub then I do not think the PRC has anything to panic about. Cool radar though nevertheless.

Yes this is wikid stuff. And to Matt, we have fixed our damm submarines, the one with the big problem was the one that we lett some europeans build
for us but we built the rest here and they have US fire control systems now so all is well thank you.

My God, OTH-T / Backscatter radars have been around for like 40 years. And I HIGHLY doubt that they could detect stealth targets (or ANY targets
flying lower than 100 meters, for that matter).
The Brits have been operating one on Crete for who knows how long. Been using it to spy on southern Russian and the middle east.. US has lots of
them.

I remember hearing about this years ago from someone i knew in the defence forces talking about this system and its ability to pick up stealth
systems. Apparently the yanks got a surprise that it could pick up their stealth aircraft so they bought into the company that designed the system so
it would not be exported or sold abroad.
thanks,

Stealth Aircraft not Immune
Edinburg is also linked to a third Jindalee transmitter and receiver at Alice Springs, which has operated as a JORN test site since 1993. McElroy says
the Jindalee radar is very difficult to jam because of the way the signal is propagated over the ionosphere. "It can also detect stealth bombers,
which are not designed to defeat the characteristics of Jindalee's high frequency radar," he said.
Stealth aircraft, such as the US Nighthawk F117A, are designed with sharp leading edges and a flat belly to minimise reflections back towards
conventional ground-based radars. However, Jindalee radar bounces down from the ionosphere onto upper surfaces that include radar-reflecting
protrusions for a cockpit, engine housings and other equipment.
Group Captain Hockings says stealth aircraft are coated with special radar absorbing material to avoid detection by conventional microwave radar. But
the Jindalee radar uses high frequency radio waves, which have a much longer frequency than microwave radar. "Unless designed to be stealthy to both
microwave and HF radars, (stealth) aircraft would not evade detection by JORN," he said.
Defence contractors are due to hand JORN over to the RAAF at the end of next year.

the collins are fixed and have been successful in exercises against the US navy. It'd be able to kick commie ass  . cost a fortune though in the
end.

This is very interesting and a good example that we should all do more to learn more about what we are doing down here. Makes me feel a whole lot
safer.

Come on Aussie, come on come on.
He he. Had to do that.
It is true we dont often recieve information about Australian technoligies( military tecnologies that is ).
Mind you, we are bound to have a bunch of projects under the hood no one knows about. Just like any other country.
I think the reason this radar suprises people is that most of the attention is always on the US. US militry this, US military that. ( most beefed up
by possible UFO connections ).
It really isnt that suprising that our goverment and armed forces would employ such strategic defence inititives. If a major war did occur we would be
a prime target being the largest main land mass in the southern hemisphere. Our location makes an ideal military staging point to the rest of the
world, plus we have quite a number of natural resources.(uranium etc. not sure about how much oil we have though... )

You are right it just isn't however at the front of mind for most of us. We are always interested in what is happening in the rest of the world and
give scant thought to our own.
I guess with the constant implied 'threat' we have from the north it makes sense that we would have leading edge defence initiatives in place and
constantly being built up. You are right that we do have a little 'gold mine' down here.
