This application provides a channel angle estimation method, apparatus, electronic device, and readable storage medium, comprising: acquiring a discrete beam set of a preset angle domain and the pointing angle, radiation pattern, and received power corresponding to each beam in the discrete beam set; determining a center beam and acquiring the power difference ratio between the center beam and a target neighboring beam, wherein the center beam is the beam corresponding to the larger value of the received power, and the target neighboring beam is one of the adjacent beams surrounding the angle domain of the center beam; mapping the power difference ratio to an angle offset according to the radiation pattern corresponding to the center beam; and correcting the pointing angle corresponding to the center beam according to the angle offset to obtain the estimated angle. This improves the angle resolution while maintaining existing stepping. Furthermore, it only requires amplitude / power data to operate, with low dependence on phase and strict calibration. It also eliminates the need for eigenvalue decomposition or large-scale iteration, facilitating real-time implementation on existing host computers or embedded processors.
