摘要
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.
