Modeling the Algorithm for Determining the Coordinates of Radio Radiation Sources Using the Maximum Likelihood Method in TDoA Systems

This paper presents the synthesis of the radio radiation sourse trajectory estimation algorithm. Multiposition radar systems are considered. The proposed algorithm is designed to find an estimate of the trajectory parameters as a deterministic function on the time interval. A polynomial model is chosen as the deterministic function. The algorithm is based on the maximum likelihood method. The main advantage of the proposed algorithm is a a fuller use of the information contained in the observations, which allows increasing the accuracy compared to traditional algorithms that do not use part of the input data. In the work presented simulation, which showed the performance of the algorithm and assess the effectiveness of its work, assessing the accuracy of determining the radio radiation sources coordinates. It is shown that the algorithm allows to determine the state vector estimation in conditions of incomplete marks.
