| 摘 要： | 雷达探测的距离、方位角与目标应答的高度属于两个不同坐标系，无法使用坐标变换
公式进行定位，为此提出了一种迭代求解方法。首先采用几何法求出雷达探测坐标系
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
明了经度和纬度的定位误差均小于0.000 02°。

| 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. |
