The impedance of plane material is made equal to the impedance of air,in this way the waves sent by radar does not reflect by material of plane and pass through plane and do not come back to radar.That is why,plane remain invisible to radar.This material was invented by a PHD proffesor in UET Lahore Pakistan.
The F-117 Nighthawk cannot be detected by radar.

Both the F-22 and the F-35 are stealth capable aircraft.
i flew under the radar..... come on

airplane..bwahahahaha....
Submarines will retreat to the depths if they are detected by radar. Note that radar can only detect a submarine if they are on the surface or if they have a mast or periscope sticking up out of the water. Radar has a terrible time trying to penetrate water, so if a submarine is detected because something is sticking up out of the water, the submarine will submerge to get some depth. Radar can't detect it down there. Also, the submarine will be trying to get out of the area and become "lost" in the ocean where it cannot be detected or located.

Radar is a technology which detects objects by bouncing radio waves off of them. It was brought into widespread use during the second world war as a way of discovering oncoming aircraft. However, low-flying aircraft could not be detected by radar, hence they flew "under the radar", that is, low enough not to be detected. Something which is "under the radar" is therefore something which cannot be detected. Often it is used for something which is too small or apparently insignificant to be detected by whatever means are being used to detect it.
Made from a Composite Material. Strong light and not able to be detected by the radar.
