Abstract: A method of direction finding (DF) positioning involving main lobe and grating lobe identification in a wireless communication network is proposed. A receiver performs DF algorithm on radio signals associated with multiple antennas over a first channel frequency and estimates a first set of DF solutions. The receiver performs DF algorithm on radio signals associated with multiple antennas over a second channel frequency and estimates a second set of DF solutions. The receiver then identifies the correct DF solution (e.g., the main lobe direction) by comparing the first set of DF solutions and the second set of DF solutions.

Abstract translation: 提出了一种在无线通信网络中涉及主瓣和光栅识别的方向查找（DF）定位方法。 接收机对与第一信道频率上的多个天线相关联的无线电信号执行DF算法，并估计第一组DF解。 接收机在第二信道频率上对与多个天线相关联的无线电信号执行DF算法，并估计第二组DF解。 然后，接收机通过比较DF溶液的第一组和第二组DF溶液来识别正确的DF溶液（例如，主瓣方向）。
