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.

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.
