A Method for Determining the Spectral Parameters of Point Objects by a Multispectral Television System under Conditions of Limiting the Image Signal

It is proposed to use a multispectral television system to evaluate the spectral parameters of point objects. A model of a television system is considered and key parameters affecting the solution of the problem are identified. A method for estimating the level of an optical signal in each spectral range is proposed. As a result of modeling, it was shown that the center of gravity method gives a significant error in determining the photocenter of a point object, while limiting the signal level. An increase in the ratio of the radius of the scattering circle from 0.8 to 2 significantly reduces the error in determining the level of the optical signal from 5.4 to 1.1 times.
