The diverterless supersonic inlet ( DSI ) enables an aircraft to reach Mach 2.0 with a simpler intake than traditionally required, and improves stealth performance by eliminating radar reflections between the diverter and the aircraft's skin.

However, the real breakthrough in stealth technology was to shape the aircraft so that any radar reflections that do occur are deflected away in one direction so that they never return to the source of the signal.
33.
It is also possible for the ground station to receive direct radar reflections from the target ( rather than the data downloaded by the missile ) and combine the two sources of information to generate the interception course.
34.
The Forward Acquisition Radar ( FAR ) would be positioned ahead of the Zeus bases to provide UHF between 405 495 MHz, allowing it to detect a 1 square metre radar reflection at or a more typical 0.1 m 2 target at.
35.
In the case of the Sputnik flying through the ionosphere at high velocity and surrounded by a naturally occurring plasma shell, there are two separate radar reflections : the first from the conductive surface of the satellite, and the second from the dielectric plasma shell.
36.
The anti-radar methods developed under Rainbow consisted of, first, a diffusing coating for the fuselage, and, second, a series of wires strung along the fuselage and the wing edges that were supposed to cancel out radar reflection from the airframe by " broadcasting " a similar return but out-of-phase.
37.
These were not a feature on the early A-3 design; Dr . Frank Rodgers of the Scientific Engineering Institute, a CIA front organization, discovered that a cross-section of a sphere had a greatly reduced radar reflection, and adapted a cylindrical-shaped fuselage by stretching out the sides of the fuselage.
38.
Radar traces also seemed to register the presence of an object, which Ray Bowyer believed to be correlated with the position and time of the sighting . however, could not establish a definite link, as the radar reflections of passenger ferries may have affected at least some of the readings.
39.
A key improvement was the introduction of computer models used to predict the radar reflections from flat surfaces where collected data drove the design of a " faceted " aircraft . Development of the first such designs started in 1975 with " the hopeless diamond ", a model Lockheed built to test the concept.

The difficulty in making a canard aircraft " stealthy " applies just as much, perhaps more, to an aircraft with a non-moving canard as with a moving canard . ( A moving canard can be swept backwards in cruising flight and the sweep provides reduced radar reflection . ) t ) " 22 : 36, 19 August 2010 ( UTC)
