FIELD: aviation.
SUBSTANCE: invention relates to means for guiding an aerial target. Method is intended for guidance of a carrier with an optical homing head on the target. Light from target in air through lens is projected onto receiver. Signals from pixels of the photosensitive matrix are recorded and recorded in stages. Starting from the first row of the Y matrix, signals from pixels are processed, signals from pixels in the next line are recorded simultaneously with processing signals from pixels in the current line. H values of the signals from each pixel are averaged. Derived values of H are converted depending on brightness of the target relative to the brightness of the background, and the difference H of the averaged and non-averaged signals is determined. Starting from the beginning of the current line, determining the pixel number X1, for which the value H becomes positive, the maximum positive value Hm, the pixel number X2, after which the value of H in the current line is not positive, the number of the current line Y is recorded in memory X1, Hm, X2, Y. Next row of the matrix is processed to determine the values X1, Hm, X2, Y. If value Hm of the value recorded for the previous line is exceeded, new values X1, Hm, X2, Y are overwritten in memory, upon completion of signal processing of all rows of the matrix, target coordinates are determined as (X1 + X2)/2 and Y and corresponding control signals are output to carrier actuators. Technical result consists in reduction of computational load of signal processing device, reduction of number of operations of storing and transmitting data arrays, faster processing of images obtained by OGS simultaneously with reception of images, higher stability of operation for coloring of target and emission of light traps.
EFFECT: invention enables to solve the problem of accelerating the search for an aerial object, increasing resistance to the use of masking of the target, and issuing a signal when a given distance to a target of known size is achieved.
