信号强度值定位模拟，包括距离测量，距离拟合曲线和高斯滤波处理，以及各种模拟分析-Signal strength value localization simulation, including distance measurement, distance fitting curve and Gaussian filtering processing, and various simulation analysis

Starting Maxwell’s equations, we derive a sensor model for three-axis magnetometers suitable for localization and tracking applications. The model depends on the relative position between the sensor and the target, orientation of the target and
