| 摘 要： | 当工作于实际数据时，由于存在着多种噪声，导致了天文像复原迭代位移叠加法中的噪声偏差项，为消除这些噪声偏差项的影响，分别讨论了在观测目标和参考星的斑点数据期间由大气视宁度差异引入的系统误差和探测器严重的附加噪声产生的偏差，并给出了对这些噪声偏差项的补偿方法。

| Abstract: | Because there are many kinds of noise, the noise bias terms are introduced in the iterative shift and add method for astronomical image reconstruction when working in real data. To overcome the influence of the noise bias terms, the system error involved by the differences of the atmospheric seeing during the observation of the speckle data of the object and referenc star; and the bias come from serious additive noise of the detector were discussed. The methods for the compensation of these noise bias terms were given. |
