Abstract

Introduction. The concepts of constructing promising radar systems (radars) show that these will be integral type complexes. The creation of such systems implies the presence in their composition of an information system consisting of channels that produce a functionally completed procedure for processing signals and information to solve a definite task.Aim. Development of a target coordinate correction algorithm based on spatial orientation information.Materials and methods. The tasks were solved by methods of mathematical analysis and numerical modeling. To justify reliability and performance of the proposed algorithm, a model was developed. The model allowed one to obtain accuracy characteristics of the algorithm.Results. As a result of the simulation, the accuracy characteristics of the target coordinate correction algorithm based on spatial orientation information were investigated. It determines the quality of building of the target trajectory and the quality of the target tracking system. The structure and the description of the developed algorithm were given, an implementation option was shown. The results of estimation of the accuracy of the algorithm were presented.Conclusion. As a result of the analysis of the target coordinate correction algorithm based on information about the target’s spatial orientation, as well as modeling of its operation, a conclusion about the reliability and the performance of the proposed algorithm was drawn The presented data of experimental studies on the accuracy characteristics of the proposed algorithm showed the feasibility of the decisions made. The presented results allow one to determine the most appropriate and effective way to develop simplified versions of the algorithm.
