Web为进一步提高传感器节点间距离的测量精度,分析了基于TinyOS的TDOA测距方法的误差来源,提出了路径平均温度补偿、时间因子补偿和位同步补偿等误差修正方法,建立了以最小二乘法为基础的误差修正数学模型.实验结果表明,修正算法及所建立的数学模型能有效抑制测量误差,提高测量精度. WebBy combining TDOA and FDOA measurements, instantaneous geolocation can be performed in two dimensions. It differs from TDOA in that the FDOA observation points must be in relative motion with respect to each other and the emitter. This relative motion results in different doppler shifts observations of the emitter at each location in general.
