的俯仰角初始值，然后直接利用坐标变换公式给出求解的迭代算法。Matlab仿真数值实例表

| Abstract: |
| As the detection distance,azimuth and altitude are in different two coordi
nates, the positioning of the target can not be realized by coordinate transform
ation.
So, an iterative method is presented for fusion positioning. Firstly, the initia
l v
alues of elevation of spherical coordinate are solved by geometric arithmetic.
Secondly, the iterative scheme is formed by coordinate transformation. A numeric
al example in Matlab software shows the positioning error of both the
long
itude and the latitude is less than 0.00002 degree. |
