Using methods of digital image processing, variational calculus, automatic control theory and probability theory, a mathematical model of the thermovision imaging seeker (TIS) of an air-to-air guided missile has been developed, designed to assess the effectiveness of the use of optoelectronic pressure equipment and complexes in protecting aircraft from high-precision weapons. A general description and block diagram of the mathematical model, a brief description of its main blocks and the order of their interaction are given.

An illustrative example of the transformation of the input images of the phono-target (interference) situation in the TIS with background compensation, determination of the target position in the image, image segmentation in the interests of recording the standard, the results of the evaluation of the range and dynamic characteristics of the TIS, as well as an analysis of the calculated characteristics of the TIS obtained during the simulation.

Based on the analysis of the results obtained and their comparison with the achieved characteristics of the TIS of this class, the conclusion is made about the adequacy of the developed mathematical model and the expediency of its use in solving the problems of evaluating the effectiveness of modern and promising aviation means and complexes of optoelectronic suppression.
