What is stealth definition?

Stealth refers to the quality of being undetectable or unobservable. It is a design philosophy aimed at reducing the visibility of an object or system by reducing its acoustic, thermal, and electromagnetic signature. It is often applied to military and surveillance technology, where the goal is to remain undetected by enemy radar, sonar, or other detection systems. Stealth technology includes design features such as specialized radar-absorbing materials, heat-dissipating coatings, and advanced sensors that enable an object to detect and evade detection. The term "stealth" can also be used more broadly to describe the ability to operate covertly or clandestinely, avoiding detection or attention.
