Webb机译： 近年来，诸如到达时间（toa），到达时间差（tdoa），接收信号强度（rss）和到达角（aoa）等多种测量已用于目标定位。 在本文中，考虑了基于二维aoa的目标定位。一种称为复杂aoa（caoa）的方法对基于aoa的定位进行了有趣的实验，表明交集的准确性与传感器和目标的部署相关。 WebbLocalization accuracy is highly affected by non-cooperative source and multipath phenomena, making the problem harder to handle. A non-cooperative target situation cannot obtain the time of arrival (TOA). Therefore, traditional precise positioning methods fail in this scenario.
