按照KC Ho 的一篇论文Source Localization Using TDOA and FDOA Measurements in the Presence of Receiver Location Errors_ Analysis and Solution写的仿真代码，用于3基站以上对固定目标进行定位，方法是两步最小二乘，实际上第二步完全不能用，不知道是不是自己写的有问题，欢迎讨论~(According to the paper "Source Localization Using TDOA and FDOA Measurements in the Presence of Receiver Location Errors_ Analysis and Solution" written by KC Ho, I write the code for simulation, the method is the least square, in fact, the second step is completely out of use, I do not know whether it is my problem or not, if you have any idea, welcome to discuss)
