摘要
无源定位中时延估计方法很多.介绍了时延估计的相关原理,并比较了现有估计方法的优缺点,提出了提高估计精度的方法,阐述了时延估计的发展趋势。
There are many kinds of methods of time-delay estimation（TDE） in passive location. This paper introduces the correlation principle of time-delay estimation（TDE）,and compares the merits and demerits of known estimation methods, presents the methods to improve the estimation accuracy,expatiates the development trend of TDE.
