Tracking Principle and Simulation for Roll-Pitch Strap-down Seeker

The tracking principle of roll-pitch strap-down seeker is analyzed. The instruction angular velocity to isolate the body disturbance is derived from the rigid body rotation kinematics for roll-pitch strap-down seeker. The tracking control instruction of the roll-pitch strap-down seeker is analyzed through coordinate transformation. By taking the roll-pitch two-axis platform dynamics model and torque motor model into consideration, an integrated strap-down and tracking seeker model is established. Then, simulation of the integrated model is implemented under Matlab/Simulink environment. The simulation results show that the integrated model is feasible.
