Probability Ellipses Error Analysis of Time of Arrival Location
摘要
Abstract
Time of arrival(TOA) passive location offers precise location,but the location errors are very different in different areas,and more importantly,the shape and distributing of error area is very complex.The error radius and error acreage cannot denote the significance well and truly for military actions.The probability ellipse is introduced to describe targets' position error,it can denote location error of anomalistic distributing area,and is very useful for military affairs.In addition,the arithmetic for location errors in different areas is presented.关键词
