A signal receiving method and apparatus, a computer readable storage medium and an electronic device are disclosed. The signal receiving method includes: acquiring a maximum scanning angle range of a phased-array antenna; and reducing the maximum scanning angle range by a binary search method, based on power of signals received by the phased-array antenna, until a difference between a maximum and a minimum of a reduced scanning angle range is less than a set value; and using the reduced scanning angle range to receive a signal.
