Abstract In this paper, the implementation method of mini missile proportional guidance guided by combination of the strapdown photoelectric seeker and MEMS inertial measurement unit is studied; and a method of extracting lineofsight angular velocity by using mathematical decouping algorithm and the least square fitting is proposed. Numerical simulations show that the method has good performance in suppressing measurement noise and counter attitude disturbance. Compared with the conventional virtual tracking loop decoupling, the proposed method has higher output accuracy of line-of-sight angular velocity.
