Abstract: 
A method of parametrical identification of optical modulation transfer function is developed with the use of the direct way on the basis of the method of least squares (LSM). The LSM's feature is concerned with solving nonlinear equations, which requires difficult computations. Parameters estimation algorithm of optical transfer function (OTF) is developed and unknown coefficients of the real atmosphere OTF are determined. Our results can be applied to the preprocessing and atmospheric correction of high-quality aerospace images.
Keywords: correction of high-quality aerospace images, nonlinear equations, optical transfer function
