What is stealth technology and how does it work?
To understand stealth technology, we need to know about the basic working principle of a radar. A radar sends out electromagnetic waves, which reflect on an obstruction and return. This signal is processed in order to determine the exact position, size and direction of target.
What is a stealth aircraft called?
So the accurate term for stealth aircraft is ‘low-observable’ aircraft. Stealth technology works on the principle of eliminating radar reflections. This can be done by either The radio waves are electromagnetic waves of varying frequencies.
How does stealth technology make an aircraft invisible to radar?
So from this we can learn that stealth technology doesn’t make an aircraft invisible to radar but it delays the detection of the aircraft until it is too late for the enemy. So the accurate term for stealth aircraft is ‘low-observable’ aircraft. Stealth technology works on the principle of eliminating radar reflections. This can be done by either
What are the disadvantages of stealth aircraft?
Stealth aircraft are visible when they open their weapons bay doors to release their weapons. One of the biggest disadvantages is its extremely high manufacturing, operational and maintenance costs. The Radar absorbent coating is extremely fragile and needs to be replaced after being exposed to combat or harsh weather.
