Multistructural Method of the Triangulation Estimation of the Motion Parameters of a Radiating Target under A Priori Indefiniteness Assumptions

Abstract

Based on the multistructuredness and clustering principles, as well as the filtration theory, we develop a new estimation method for the motion parameters of a radiating target under the assumption of a fundamental indefiniteness of the operating conditions for the triangulation measurement system. The method admits anomalous measurement errors in the measurement channels (the azimuth and the angle of elevation) of particular system locators such that neither the number of uncertain channels neither the time moments of the appearance of these errors are known (only the greatest possible number of uncertain channels is known). The method is implemented in the stochastic variant with or without the participation of an operator. The implementation does not require the traditional extension of the space of states. We provide the results of the comparative analysis demonstrating the efficiency of the method.
