PROBLEM TO BE SOLVED: To provide a semiactive laser guide system, improving the hitting accuracy of an airframe and extending a target detecting distance without any increase in size of the system. SOLUTION: In this semiactive laser guide system, a laser beam Lp from a laser irradiation means 1 is applied to the target X, the reflected light Lr reflected on the target X is detected to compute a target angle of the target X, and the airframe is guided and controlled according to the target angle. The laser irradiation means 1 includes a modulating function of scanning an irradiating laser beam Lp to the target X and changing the pulse cycle of the laser beam Lp corresponding to the scanning angle, and the airframe 10 includes a function of recognizing a scanning angle from the pulse cycle obtained by demodulating the detected reflected light Lr, and obtaining a correction angle from the scanning angle to correct an incident angle of reflected light detected and obtain a target angle to the target X.
