PROBLEM TO BE SOLVED: To provide a method for detecting the incident direction of laser scattering light in laser guide control of a projectile in which the incident direction of the scattering light of laser beam is detected without being affected by the environment and data processing algorithm is simplified. SOLUTION: Moving range of a projectile A is set based on the inscribed circle of a regular triangle and minimum and maximum reference anglesΨmin,Ψmax between two laser beams are set. Setting of threshold value is eliminated by selecting one of sensors C1-C8 detecting maximum receiving light intensity and specifying the incident direction of laser scattering light. Data processing algorithm is simplified by removing the data of an adjacent sensor based on the minimum reference angleΨmin and finally specifying the incident direction of laser scattering light based on the maximum reference angleΨmax.
