- Acoustic_mirror abstract "An acoustic mirror is a passive device used to reflect and perhaps to focus (concentrate) sound waves. They were used during World War I to detect troop movements and artillery, and were a major area of study as an anti-aircraft early-warning device prior to the introduction of radar. A wide network of large acoustic mirrors was in the process of being set up in southern England when the project was suddenly canceled as the Chain Home system evolved.Acoustic mirrors contrast with the much shorter-range acoustic location systems consisting of megaphone-like devices. These are used to locate the object with some degree of accuracy; acoustic mirrors provide limited location information by offering longer range detection.".
