这意味着可以利用它们相当精确估计它们的距离(因而可以估计他们所在的星系的距离)。
That means they can be used to estimate quite precisely how far away they (and thus the galaxy they inhabit) are.
提出了一种利用基于距离参数的最小二乘滤波器群的纯方位跟踪目标参数估计器,该估计器是由若干个处地不同的距离区间上的加权最小二乘滤波器组成。
In this paper, a new bearings only tracking approach, which consists of a set of weighted least squares filters (LSF) each with a different initial range estimate, is proposed.
