摘要
为更好地解决在时间和方向测量精度低的情况下,仅利用到达频差(frequency difference of arrival,FDOA)进行定位求解的问题,对基于FDOA的无源定位算法现状和发展方向进行分析。在阐述FDOA无源定位基本原理的基础上,分析了定位问题的本质和定位算法的分类方法,结合基于定位观测量数据的定位算法和接收信号直接定位法的国内外研究现状,分析了FDOA无源定位算法存在的问题,指明了基于FDOA的定位算法的未来研究方向。该研究可为基于FDOA定位算法的研究提供参考依据。
In order to better solve the problem of passive localization using frequency difference of arrival(FDOA)only,in the case of low time and direction measurements precision,the research status and development direction of passive localization methods based on FDOA are analyzed.On the basis of expounding the basic principles of FDOA passive localization,the nature of localization problems and the classification of localization methods are analyzed.The problems in the localization methods using measurement data and the direct position determination methods using received signals are analyzed respectively,through the summary and comparison of research status at home and abroad,and the future research directions of the FDOA-based localization methods are pointed out.This study can provide reference for the research of passive localization methods based on FDOA.
