Least Square Models with 4-Dimesional States and Analysis for Bearings-Only TMA

建立了纯方位系统TMA四维状态的最小二乘模型,详细给出了非线性最小二乘算法的迭代公式,分析了非线性最小二乘模型、线性最小二乘模型可解的必要条件,以及非线性最小二乘模型与极大似然模型的等价性。

In this paper least square （LS） models with 4-dimensional states are presented and detailed nonlinear LS algorithm are given for Bearings-Only Target Motion Analysis （TMA）. Solvable necessary conditions of NLS and LS models, equivalence properties of NLS and maximum-likelihood models are analyzed.
