     SUBSTANCE: invention relates to radio engineering and can be used in ground-based systems of active survey single-position radar for detection and location, motion parameters and trajectories of air targets moving in space. To achieve technical result, movement of each air target is considered as a sequence of movements along polyhedral surface approximating to beam specified by vector of inclined range of target. To form trilateration system, auxiliary points B are used on abscissa and D on ordinate axes spaced by distance d from coordinate origin, and calculating range values R from them to the target, rectangular coordinates of the targets, forming the size of the target selection zones by range and angular coordinates. At repeated survey, values of inclined distances, azimuths and angles of targets are measured, and new samples are identified to initial sections of trajectories of previously detected targets. Values and coordinates are calculated for each tracked target. Using extrapolated values of rectangular coordinates from outputs of Kalman filters for formation of selection zones in points A k+2  of trajectories of targets. Based on the results of subsequent surveys, trajectories of targets are detected by the criterion "three of three", values of distances traveled by targets during the time of scanning, modules of velocity vectors and spatial course angles, as well as flight altitudes and diving or pitch-up angles are calculated. In subsequent surveys coordinates of targets are measured and tracking and construction of their trajectories.
