中文说明：自己编的无源定位编码，多普勒原理应用FDOA w为输入三行三列矩阵，为三个固定观察站的坐标。v为输入三行三列矩阵，为三个观察站的x方向，y方向，z方向的速度。！！！注意fdoa三个观察站必须有速度，不然就产生不了频差！！！I为一行两列矩阵，为收到的频差。f0为目标基站的频率，这里我随便设的数。c为光速r为地球半径此程序要求三元高次非线性方程组解，我选择用牛顿迭代法。
English Description：
Based on the Doppler principle, FDOA & nbsp; W is used as the input three row three column matrix and the coordinates of three fixed observation stations. V is the input three row and three column matrix, which is the velocity in X direction, Y direction and Z direction of three observation stations.!!! Pay attention to FDOA three observation stations must have speed, otherwise it will not produce frequency difference!!! I is a matrix of one row and two columns, and I is the received frequency difference. F0 is the frequency of the target base station, which I arbitrarily set here. C is the speed of light, R is the radius of the earth. This program requires the solution of three dimensional high-order nonlinear equations. I choose Newton iterative method.
