Abstract: Embodiments of the present invention disclose a propagation path search method. In one embodiment, the method includes: defining a target three-dimensional object, where the target three-dimensional object is configured to describe full space; setting a signal transmission point in internal space of the target three-dimensional object to perform initial beam modeling of a signal point source, where the signal transmission point is used to transmit an initial beam; tracking the initial beam to determine a propagation manner generated by the initial beam in the three-dimensional object; and determining that a path corresponding to a target beam is an effective path when the target beam reaches a signal receiving point, where the target beam is included in the initial beam, or is obtained after the initial beam is split or changed.
