【摘要】 针对传统的无源时差定位算法定位精度不高的缺点,本文提出了一种基于平面相交(PI)的迭代算法。该方法结合了(PI)算法计算速度快优势,同时吸收了Taylor算法迭代求值的思想,将两者数据进行融合定位。仿真结果表明,与单一(PI)算法相比,该方法的定位精度显著提高。更多还原

【Abstract】 In allusion to the low accuracy of traditional passive TDOA location algorithm,a new mothod baseing on plane intersection (PI) and iterative algorithm is employed in this paper.The mothod combines the computing speed advantage of (PI) algorithm,absorbs the iterative evaluation theory of Taylor algorithm,and integrats them to position.The simulation results show that comparing to single (PI) algorithm,this method significantly improve the positioning accuracy,and it also can be used when all the receiving stations are in the plane.更多还原
