Influence of Missile Spin on Infrared Seeker's Rosette Scan Pattern

Aim To study the feasibility of applying rosette scan infrared seekers to spinning missiles. Methods The number of rosette scan petals required for the instantaneous FOV to cover the total FOV was calculated and the effects of the gyro rotational frequency, motor rotational frequency and missile spin rate variations on rosette scan patterns and frame frequencies were predicted. Results and Conclusion Rosette scan infrared seeker could be applied to spinning missiles by adding an on board sensor for body spin rate measurement and feedback control of the gyro and motor rotational frequencies.
