Abstract: FIELD: evaluation of quality of opticoelectronic systems of distant sounding by way of measurement of their resolution on location. SUBSTANCE: aerial survey of test object (line mire) is conducted and its image is obtained. Transformation x o  is executed on central part of image with arrangement of signals and isolation of group of four maxima. Then one switches to system of coordinates related to rectangle of mire, amplitude A i  of lines in groups in image (i=1, n) and their area S fi  are computed. Later root-mean-square deviation of noise in image is calculated and signal-to-noise ratio Φ i  is computed by formula   where k 1  is coefficient taking into account number of stripes in group of lines. Setting probability of detection of lines one finds value Φ       *   i        which meets in the greatest degree standard decoding model. Width L of stripe on location that can still be differentiated visually in image is obtained by formula L = ((Φ       *   i       ) 2 σ 2 ε i M)/(k 2 •A i ),, where k 2  is coefficient taking into account number of lines in each group and area of line in image; ε i  is length of stripe on location for selected i-th group. Obtained width of stripe on location determined resolution value of opticoelectronic system of distant sounding on location.
