摘要
针对工程应用中塔康(TACAN)数据在进行惯导参数校正过程中存在着多种坐标变换的问题,根据校正算法的特点提出了一系列坐标变换方法,将目标相对TACAN信标台的反方位角和斜距等信息变换到WGS-84大地直角坐标系,并利用Matlab仿真详细估计了坐标变换所引入的误差,结果表明,坐标变换后的定位精度完全满足工程应用要求。
TACAN data is often used to adjust the inertial navigation parameter in which many sorts of coordinate transformation are concerned. Based on the adjustment features, this paper provides a series of coordinate transformation algorithm. Its ultimate goal is to use the information of TACAN anti - azimuth and inclined distance to calculate the object's coordinate in WGS - 84 system. The transformation error is analysed in detail with Matlab simulation. The result shows the positioning precision after coordinate transformation satisfies the engineering application.
