| 摘 要： | 在移动节点射频定位技术基础上，根据自主移动节点运动的特点，提出一种能够减轻非视距NLOS影响的定位算法nLAEL．该算法首先利用移动节点的速度信息，构造相对定位轨迹；然后通过相对定位轨迹和射频定位的比较实现对位置和方向的估计，获取定位结果；最后估计射频定位精度，区分出失真的射频定位结果，以减小NLOS的影响．本算法计算简单，是一种实用的移动节点定住方法．仿真实验结果证明了算法的有效性．

| Abstract: | An effective location method-nLAEL(Location and Attitude Estimation based Localization) was present to obtain accurate position estimation for mobile nodes and mitigate the influence of the NLOS propagation.Firstly,the relative trace was obtained by using velocity information.And then the final location was acquired while the global optimum solution was obtained by comparing relative localization and radio localization.Finally,a threshold was set to distinguish obvious deviation from radio localization.The ... |
