Research into Seeker Servo System of Anti-ship Missile under The Jamming Condition

The seeker servo system of anti-ship missile plays an important role for targ target tracking and target parameters measurement, its precision directly influences accuracy of anti-ship missile. Firstly,according to the structure of seeker servo system et searching, the guidance , angle stabil- ity loop,angle tracking loop and angle designation loop of seeker are analyzed under the jamming condition,the mathematical model is established for seeker servo system;the Kalman filter is intro- duced in angle tracking loop to improve the anti-jamming capability of seeker and to provide accu- rate target data for system through filtering; then combined with actual engineering, the Simulink control model of seeker servo system is constructed and simulated dynamically;finally,the dynamic response results of the system are get. The simulation results show that the method can improve responding speed and tracking accuracy of the seeker effectively, which provides a scientific basis for the engineering design of anti-ship missile radar seeker.
