Nonlinear Least-Square Algorithms Used for TMA in Bearing-only System--The Engineering Mathematic Model and Algorithms

The method of nonlinear least-square is a kind of comparatively practical one among many methods used for TMA in bearing-only system. However, it is complex and difficult in engineering application because of its theoretical model and matched conventional algorithm. This article shows linearized least-square and establishes engineering mathematic model and algorithm, then researches on the selection of initial value deeply. Finally, the article comes to the conclusion about the method of nonlinear least-square used for TMA.
