摘要

讨论了从无源静止阵列的距离差测量中估计辐射源位置的问题。提出并分析了一种新的闭式源位置估计器——球面插值估计器。球面插值估计器产生的位置估计是加权方程误差范数的近似最小值，并且显示接近最大似然源位置估计器。

The spherical interpolation method for closed-form passive source localization using range difference measurements

The problem of estimating the location of a radiating source from range difference measurements taken from a passive, stationary array is discussed. A new closed-form source location estimator, termed the Spherical Interpolation Estimator, is presented and analyzed. The location estimates produced by the Spherical Interpolation Estimator are approximate minimizers of a weighted equation error norm, and are shown to approach the maximum likelihood source location estimator.
