Abstract�� Optical detector of strapdown seeker was fixed rigidly to the missile body, and many traditional guidance information processing methods can not be applied directly. The half strapdown seeker was studied. According to its different structure, reconstruction algorithm of the line-of-sight(LOS) rate was derived for roll-and-pitch and yaw-and-pitch half strapdown seeker. The Influence factors and error transfer relationship for extracted accuracy of LOS rate were analyzed. Then the correctness of the algorithm was verified by Simulink.
