基于TDOA的基站布局对定位精度影响分析
Analysis of the Influence of Base Station Layout on Location Accuracy Based on TDOA
摘要
Abstract
Positioning equation based on TDOA is analyzed , the nonlinear function of position error on target azimuth of sta-tion is solved by the differential operation of the equation , the specific factor which affects the positioning accuracy is found out by analysis of function .In addition, an chaotic double disturbance particle swarm optimization algorithm is put forward to solve the function for the problem that nonlinear function is difficult to solve , the algorithm can quickly find the base station layout which satisfies the minimum position error when the target position is changed , and the features are summarized which meet the minimum positioning error of the base station layout .Finally the conclusion is verified by an example .关键词
