Technology has seized everything tangible or intangible that surrounds us; alarm clocks rule our sleep, wheels make us move, pills fulfill our body needs, and not to forget the accomplishments made in the field of defense.Take the latest radar system that is virtually undetectable owing to its signals that resembles random noise. The foolproof system, developed by Ohio State engineers, could be successfully used in law enforcement, military, disaster rescue and medical imaging.
Eric Walton, senior research scientist in Ohio State’s ElectroScience Laboratory, explains:
Almost all radio receivers in the world are designed to eliminate random noise so that they can clearly receive the signal they’re looking for. Radio receivers could search for this radar signal and they wouldn’t find it. It also won’t interfere with TV, radio or other communication signals. It doesn’t interfere because it has a bandwidth that is thousands of times broader than the signals it might otherwise interfere with.The cost-effective radar system, costing less than $100, can easily penetrate through solid walls, allowing army to detect enemy hideouts without any clues.
