The triangular geometry is the basis of near field array accurate distance estimation algorithms.The Fisher expression of traditional distance estimation is derived by utilizing the Taylor series.To improve conver-gence rate and estimation accuracy,a novel iterative dis-tance estimation algorithm is proposed with differential equations based on the triangular geometry.Firstly,its convergence performance is analysed in detail.Secondly,the selection of the initial value and the number of itera-tions are respectively studied.Thirdly,compared with the traditional estimation algorithms by utilizing the Fisher approximation,the proposed algorithm has a higher con-vergence rate and estimation accuracy.Moreover,its pseudocode is presented.Finally,the experiment results and performance analysis are provided to verify the ef-fectiveness of the proposed algorithm.
