Target Motion Analysis : ウィキペディア英語版
Target Motion Analysis
Target Motion Analysis (TMA) is a process to determine the position of a target using passive sensor information. Sensors like passive '' RADAR'' and '' SONAR'' provide directional and occasionally frequency information. TMA is done by marking from which direction the sound comes at different times, and comparing the motion with that of the operator's own ship. Changes in relative motion are analyzed using standard geometrical techniques along with some assumptions about limiting cases. There are two different ways to execute TMA: manual and automated.
== Manual TMA ==
Manual TMA methods involve computation executed by humans instead of computers. There exist several manual TMA methods such as: Ekelund Ranging, 1934 Rule, Spears Wheel etc.
