Annotation: An algorithm for generating the trajectory of an aerial target based on flight data recorder information is described. The algorithm allows generating reliable trajectory data of aerial target motion if the flight data of the aerial target motion is incomplete. One of the problems associated with simulating the trajectories of objects in 3D space during computer simulation is considered using the example of modeling guidance algorithms for aviation weapons in various tactical conditions. Simulating the motion of an aerial target in the atmosphere is one of the significant problems in using computer models. To evaluate the functioning of aerial target guidance systems, it is necessary to simulate the motion of a real target as realistically as possible, including instantaneous changes in trajectory coordinates and all random variables accompanying motion in the real atmosphere, such as trajectory instabilities, fluctuations in angular orientation parameters, etc. The difficulty of solving this problem lies in the lack of sufficient information about the statistical motion parameters, flight characteristics, and tactical maneuvers of real targets. Modern combat aircraft are equipped with flight data recording systems that allow recording the parameters determining the functioning of the targeting and navigation complex, including the motion parameters of observed aerial targets. Based on this, an approach to simulating the motion of a real target in a computer model is proposed, which consists in generating the trajectory of an aerial target based on data from a flight data recording system capable of registering the motion parameters of the observed target. An analysis of records from modern recording systems indicates the presence of severe noise and distortion in the recorded data. To eliminate them, well-known data recovery methods described in the literature are used. However, traditional data recovery methods prove inapplicable in the presence of anomalous jumps and gaps in the data. The proposed algorithm for recovering the acquired data uses well-known filtering methods and an original algorithm for eliminating anomalous distortions in the recorded data, which together makes it possible to obtain a dataset describing the trajectory and motion parameters of the target, serving as the basis for reproducing motion in a computer model of a maneuvering target. Since the proposed data recovery method does not impose high requirements on processing system performance, its use makes it possible to automate the high-quality processing of large volumes of data for the subsequent analysis of aviation weapons employment conditions in real tactical situations.
