The paper presents a method for finding air means on a laser beam, which is based on the reception and analysis of the scattered radiation in the atmosphere of the probe laser rangefinder-target indicator to determine the direction of the optical axis of the beam and subsequent laser probing of the space in the direction of the laser beam to detect air means. Based on graph theory and semi-random processes developed a computer model that reflects the dynamics of the search aircraft on a laser beam designator-rangefinder it using passive and active optical elements locator. It was found that the model introduced in the state of physical and information to allow a reasonable interpretation of the transition probabilities and densities of the transition time (or find the status of the transition to the next) from state to state. The resulting dependence of the probability of correct target detection in various environments under-confirm the possibility of effective application of the proposed method by means of the search aircraft laser beam. A computer model of the process of finding, presented in the form of a dynamic system of interconnected inertial links with the relevant transfer functions, allows us to justify long-term requirements for the parameters of the optical locator that provides the ability to detect and determine the coordinates of the carrier laser range finder-designator to dispel the atmosphere of its radiation.
