Statement of the problem: assessment of the security of aircraft equipped with air-to-air defense systems against weapons of the "air-to-air" class with optical homing systems, using the method of mathematical modeling using images recorded in the flight experiment.

Purpose: development of an algorithm for determining the coordinates of the aircraft from the image of the reference optical radiation using digital processing and morphological analysis of images.

Results: an algorithm for tracking an aircraft based on images of reference optical radiation under interference conditions was developed, based on the methods of digital processing and morphological analysis of objects. A comparative assessment of the accuracy and speed of the developed algorithm has been carried out showing its advantages over the Hough algorithm, and high resistance to the presence of noise in images has been confirmed.

Practical significance: using the method of mathematical modeling, it is shown that when applying the developed algorithm, the average value of the error in determining the position of the aircraft is 1-2 e. resolution, which is 2 times less than when using the Ha-fa algorithm. In this case, the determination of aircraft coordinates using morphological analysis occurs 3-4 times faster. It was found that with a normalized root-mean-square deviation of the additive noise in the original image of more than 0.2, the standard deviation of determining the coordinates of the aircraft will be more than 220 el. resolution, and when applying the algorithm of morphological analysis 20 el. permissions.
