Angle measurement method and related device

The invention provides an angle measurement method and a related device, and the method comprises the steps: firstly, obtaining the first signal strength of a signal which is received by a first antenna in a first antenna group and is from target equipment, and the second signal strength of a signal received by a second antenna in the first antenna group; then, determining an incident angle range of the signal according to a signal intensity difference value between the first signal intensity and the second signal intensity; then, when the incident angle range is greater than or equal to a preset angle threshold value, determining a target antenna group according to a magnitude relationship between the first signal intensity and the second signal intensity, and switching to the target antenna group; and finally, signal transmission is carried out through the target antenna group and the target equipment so as to determine arrival angle data of the target equipment. According to the invention, the appropriate
