Noise Bias Compensation in the Iterative Shift-and-Add Method for Astronomical Image Reconstruction
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.
