[quote]A British research and development company, which claims to have invented a method to detect stealth aircraft, has clammed up on details about its technology.
Roke Manor Research has decided not to speak to the press after UK national the Daily Telegraph ran an article on the detection system. Roke claims the Telegraph misquoted the company’s head of projects. [The truth or arse covering? – you decide, Ed]
The system uses a traditional mobile phone network to detect stealth aircraft as they pass silently through the ether. Although the aircraft have advanced coatings which absorb conventional radar signals, they apparently still reflect back enough radiation emitted from mobile phone masts to be detected by special ground receivers.
The receivers are linked to a central computer which – in sync with a GPS satellite – is able to position the aircraft to within 10 metres.
The central computer could conceivably be a simple notebook operated by ground troops. Once exposed, the stealth aircraft would be easy prey for convential ground-to-air missiles.
Disabling the system would require the complete destuction of a target country’s mobile phone mast network – in reality, an impossible task.

The radar boasts one principal plus: its ability to function in the meter-wave band makes it invulnerable to homing and antiradar missiles effective in other wavebands. Secondly, the radar can detect so-called “invisible” aircraft,including STEALTH technology planes. Indeed, this aircraft’s invisibility is based on itsspecial shape, which produces an extremely small signal return. In the meter-wave band used in radar technology, an aircraft’s size is commensurate with wavelength, and its shape is no longer important. The “invisibility” of such aircraft is also due to their radio-absorbent coating. However, to attain a marked decrease in “visibility” in the meter-wave band, one must ensure a substantial increase in the thickness of the “smearing”.
Also,if PLASMA STEALTH is as real and portable as claimed,there would be no need to have aerodynamic compromises – shapes,reduced weapon loads etc.Having an electromagnetic feild around the aircraft would be far more advantageous as the probability of detection is nil wheras some amount of radiation is always reflected from the surfaces of even the stealthiest aircraft.And what about the advent of super cooled IRSTs?
What say you?Was the investment of all those $$$ into making aircraft stealthy a tad hasty?
