| 摘 要： | 提出一种近似的最大似然估计方法,用于基于测量波达角进行目标定位.通过引入一中间量,即和波达角估计相关的非线性方程可以转换成一组未知参数的线性方程.这就是近似的最大似然估计.实验仿真表明,提出的算法具有明显的优点：误差小,鲁棒性好.

| Abstract: | An Approximation of maximum likelihood estimator(MLE) for localizing a source based on AOA measurements is presented.By introducing an intermediate variable,the nonlinear equations relating AOA estimates can be transformed into a set of equations which are linear in the unknown parameters.It is an approximate realization of the MLE.Simulation experiments show that the proposed ML estimation is possessed of obvious advantages: less error and more robust to noise disturbance. |
