空间监视中设备级数据-目标对应关系确定方法

Determination of Equipment-level Data-Target Correlation in Space Object Surveillance

基于各测量弧段的方位、俯仰，通过数学变换和多项式拟合，实现以拟合系数为特征量表征该弧段的观测。进而通过比较观测值与理论值的拟合系数，完成数据-目标对应关系的确定，达到简化设备级数据-目标对应关系快速确定的目的。

Based on measurements of the azimuth and elevation of a specific pass and through mathematical transformation and multinomial fitting, observation is represented by taking fitting coefficient as the signature variable. Then, datatarget correlation is established through comparison of fitting coefficients of the observation data and the theoretical data, the purpose of which is fast determination of the simplified equipment-level data-target correlation.
