Stealth Technology
Scientifically know as
LOW OBSERVATORY.
Used in military aviation
Reduces detection range
of an air craft Similar to camouflage tactics
used by soldiers
Partial indivisibility to radar
and other detection

The first “STEALTH” aircraft
have been developed in Germany
during the last years of WWII.
This technique has also been used
in ships.
Later Americans worked on
stealth technology and succeeded.

What Is RADAR ?
8. DRK College of Engineering & Technology
Technical SeminarDate
Almost since the invention of radar, various techniques have
been tried to minimize detection
Some of the techniques used for this purpose are:
1.Vehicle shape
2.Radar absorbing material
