一种无线电台自定位算法理论探讨

Theory Research into a Radio Selflocation Algorithm

本文给出了一种通过无线电台定位的方法 ,它的显著特点是可利用普通超短波电台 ,实现快速准确自定位 ,并通过自组织数字电台网络实现位置信息的快速报知 ,系统架构类似于美军EPRLS系统。其基本原理是通过相关运算获得相位差和相应的距离差 ,并通过解双曲线方程得到位置坐标。本文采用模糊聚类方法实现双曲线方程的快速求解 ,灵活。

This paper gavel a research method about radio-location。The method of the distance measuring is designed according to the feature of the ultra-short wave radio . The system structure is similar to the American army’ Enhanced Position Location Reporting System-EPRLS. According to this method, the relevant range difference will be obtained through the phase difference which comes from the relevant operation , and the location coordinate will be obtained through the hyperbola equation . At the same time , this text will tell a good solution to the hyperbola equation , a quick solution which adopts fuzzy clustering .
