基于RSSI的三点定位测算距离，并将坐标显示在图形中-Three RSSI-based localization estimates the distance, and the coordinates are displayed in the graph

自己改编的代码，可以进行基本参量的计算（归一化阻抗和导纳，驻波比、行波系数和反射系数等），鼠标取点绘制并计算相关特性阻抗，计算距离负载d处的输入阻抗，单枝节匹配和双枝节匹配，圆图的绘制、保存图像等。且整个过程可视化~-Own adaptation of code can be calculated basic parameters (normalized impedance and admittance, VSWR, traveling wave and reflection coefficie
