摘    要:介绍了一种基于线性调频技术的nanoLOC定位芯片,利用该芯片进行测距定位实验,对多次测量数据进行拟合,将拟合后的方程系数求平均得到最终的拟合方程;并将测量值代入该方程,求得拟合后的距离值,采用拟合后的距离值进行最小二乘法定位,结合粒子滤波器滤波进行最终定位。实验结果表明,采用本算法可以达到很好的定位效果。

关 键 词:线性调频技术  nanoLOC  最小二乘法  粒子滤波器  室内定位技术

Abstract:This paper introduces a kind of nanoLOC chip that based on linear frequency modulation technology,and uses the chip for indoor positioning experiments.It uses multiple measurement values to fit several straight lines and averages the fitting equation coefficients to get the final fitting equation.Measured value is plugged into the equation to get the fitting range value.The fitting distance values are used to get the location by adopting least squares,then filtering the location result by employing particle filter,and the final position of the moving target is achieved at last.Experimental results show that the algorithm can achieve better positioning performance.
Keywords:linear frequency modulation technology  nanoLOC  least squares  particle filter  indoor positioning technology
