Abstract
To study the effect on infrared imaging seeker's target tracking of missile attitude changes, the model of a seeker in which optics system is installed in gyro rotor is built. In the model such factors as dynamic characteristics of gyroscope, noise caused by gyroscope rotation, coupling of pitching and yawing of seeker and so on are taken into accounted. Simple missile model and target model were built too. Based on the models simulation was made and simulation results show that rolling has more obvious effect on seeker's tracking target than pitching and yawing and the larger magnitude and frequency of missile's rolling movement are the more seriously seeker's output is affected, which is helpful for design of missile's control system, choice of guidance law and overall design of weapon system.
