阅读说明：本技术 使用测向特征进行资产定位 (Asset localization using direction finding features ) 是由 罗伯特·赫尔维伊 于 2019-02-28 设计创作，主要内容包括：公开了用于使具有有限RF能力的移动设备能够经由多天线定位器设备获得用于寻找对象或资产的准确方向的系统、方法和设备。移动设备向定位器设备生成获得寻找资产的方向的请求。还可以做出向多天线定位器设备获得移动设备自己的定位的请求,该多天线定位器设备具有天线阵列并且位于具有良好RF可见性的固定定位处。定位器设备识别目标资产,并使用天线阵列从目标资产接收RF信号。在每个天线处信号被检测,并相位样本被记录。相位样本数据在诸如到达角和出发角算法的角度相关函数中被使用,以计算资产的方向。(Systems, methods, and devices are disclosed for enabling mobile devices with limited RF capabilities to obtain an accurate direction for finding an object or asset via a multi-antenna locator device. The mobile device generates a request to the locator device to obtain directions to find the asset. A request may also be made to obtain the mobile device's own position from a multi-antenna locator device having an antenna array and located at a fixed location with good RF visibility. The locator device identifies a target asset and receives an RF signal from the target asset using an antenna array. At each antenna the signal is detected and phase samples are recorded. The phase sample data is used in angle correlation functions such as angle-of-arrival and angle-of-departure algorithms to calculate the orientation of the asset.)
