METHOD FOR POSITIONING USING TIME DIFFERENCE OF ARRIVAL

摘要

The present invention relates to a position detection method for targets by selecting receivers for calculating the position and setting the center between the receivers as a virtual receiving position using a reference table which contains information about the position of the receivers in multiple directions and information about the angle of arrival. Errors in position calculations are reduced and reliability in the position calculations is improved by selectively setting the receivers and the virtual receiving position. [Reference numerals] (AA) Start;(BB) Measure the time of arrival regarding an object;(CC) Measure difference in the time of arrival;(DD) Calculate the angle of arrival using the difference and the position of a receiver;(EE) Select a virtual receiving position;(FF) Determine a reference angle of arrival using a reference table;(GG) Detect the position of the object;(HH) End
