3-Dimensional Localization Algorithm Research Based on Weighted Fusion with Projected Coordinate

Abstract:

Due to the serious problem of wireless 3-Dimensional localization technology affected by geographical conditions and other signal jamming, we proposed a new weighted 3-Dimensional localization algorithm based on TDOA-AOA. In this new algorithm, we obtained two groups of 3-Dimensional projected coordinate values of every test point using joint algorithm of TDOA and AOA. Then after weighted scaling, we got the localization coordinate of the point. It is proved by multiple sets of simulation experiments that this algorithm with data weighting can effectively reduce the localization error caused by the environmental interference, and thus ensure the accuracy and effectiveness of the results.
