摘　　要：现有的传感器配准算法主要有两大类,一类是基于立体投影的二维空间配准技术,这类方法在投影时扭曲了数据,且无法估计俯仰角系统误差;一类是基于地心坐标的三维空间中的配准技术,这类方法由于在计算时很少考虑到测量噪声对传感器系统误差估计产生的影响,实际的估计效果较差。为此,通过在地心坐标系下对系统进行建模,提出了两种考虑测量噪声的三维空间传感器配准算法:一种基于合作目标,一种基于公共量测。最后通过蒙特卡洛仿真验证了算法的有效性。Until now,sensor registration algorithms can be divided into two groups： The first group is based on stereographic projection,which will lead bias into measurement and could not evaluate bias of pitch.The second group is based on ECEF,which ignores the effect of measurement noise on registration.In order to solve these problems,when measurement existing noise,sensor registration algorithms based on the ECEF are presented on two circumstances： one is based on cooperative object,the other is based on common measurement.Finally,simulation results based on Monte Carlo prone that the effectineness of the proposed algorithms.
