In article the method of indemnification of an atmospheric background and a way of detection of thermal objects on an atmospheric background by means of infra-red heat direction finders with a sight wide field is stated. On the basis of a way the algorithm of the two-dimensional spatial filter which can be realized programmatically in the video processor heat direction finders. The algorithm allows to automate process of detection of air targets (planes, helicopters, cruise missiles, unpiloted aircraft, etc.) and to provide the display of their video images to the monitor of the video control device in the binary kind.
