Thesis Abstract and Dissertation Abstracts

The ability to move around undetected is called "stealth”. It is very important in modern warfare. Stealth technology also termed LO technology (low observable technology) is a subdiscipline of military tactics and passive electronic countermeasures, which cover a variety of techniques used with personnel, aircraft, ships, submarines, and missiles, to make them less visible (ideally invisible) to radar, infrared, sonar and other detection methods. The U-boat U- 480 may have been the first stealth submarine. It featured a rubber coating, one layer of which contained circular air pockets to defeat ASDIC sonar. Have you ever dreamed about becoming invisible? Or about making something else invisible, like the mess all over your room?

Invisibility may sound like the stuff of science fiction, but in reality, military vehicles, like planes and ships, can be made less observable, or even invisible, to different detection methods—like radar, sonar, or infrared sensors—by using stealth technology. Stealth technology is based on the principle of reflection and absorption that makes the objects stealthy.
