Abstract: This application describes a positioning method, apparatus, and system. The positioning apparatus includes an antenna selection circuit, a receiving processing circuit, and a processor, and the antenna selection circuit is coupled to the processor through the receiving processing circuit. The antenna selection circuit is coupled to an antenna array that includes M*N antenna elements, and the antenna selection circuit selects different combinations of antenna elements from the antenna array, where each combination of antenna elements includes L antenna elements. The processor controls the antenna selection circuit to select a combination of antenna elements from the antenna array. The receiving processing circuit receives an answer signal from a tag through L antenna elements selected by the antenna selection circuit, and processes the answer signal. The processor then positions the tag based on processed data.
