Abstract: A mobile terminal, and a locating method and device are provided, wherein the mobile terminal includes a first antenna, configured to transmit a first signal to an anchor node, wherein the first signal is used by the anchor node to detect the signal strength of the first antenna; a second antenna, arranged with the first antenna according to a preset angle and configured to transmit a second signal to the anchor node, wherein the second signal is used by the anchor node to detect the signal strength of the second antenna. The preset angle enables the coverage of the first antenna and the second antenna to be overlapped to some extent. The signal strength of the first antenna and the signal strength of the second antenna are used for determining a location of the mobile terminal.

Abstract: Provided are a system and a method for determining an angle. The method includes: determining differences between signal strengths of incident waves received by a first directional antenna of an anchor node from a tested node and signal strengths of incident waves received by a second directional antenna of the anchor node from the tested node at multiple angles, wherein the first directional antenna and the second directional antenna are mounted at a same point, and an area formed by the first directional antenna is partially superposed with an area formed by the second directional antenna; and taking an angle corresponding to a minimum difference in the differences as an angle between a line connecting the anchor node and the tested node and a horizontal reference line. The present technical solution achieves the technical effect of positioning a target accurately when the positioning device is low in complexity.
