Abstract Firstly, the working principle and deficiencies of gyro-stabilized seeker are analyzed. Secondly, the coupling dynamic model of gyro tracking system is established, and transfer functions of the decoupling loop and tracking loop are derived. Based on the dynamic stability, the key parameters affecting the decoupling and tracking performance of the seeker are pointed out. Finally, the accuracy of the dynamic model is verified by comparing the results of mathematical simulation and Hardware-In-Loops simulation. The modeling and simulation of seeker can provide theoretical support for the design and development.
