N2 - This paper proposes a guidance algorithm based on strap-down devices to obtain more accurate guidance information for small missile system. This paper establishes a mathematic model of inertial devices to get the navigation information of the SINS. Then the calculation results of the navigation system are used to establish the mathematical model of the inertial line-of-sight angular velocity of the strap-down seeker. So, the extraction of guidance information can be realized. In order to reduce the influence of system noise, this paper designs extended Kalman filter and unscented Kalman filter to filter the guidance information separately and compares these two filter results with the data from the track generator. The simulation results show that the guidance algorithm is effective and can obtain the guidance information to meet the requirements.
