The disturbance rejection rate parasitic loop in strapdown imaging seeker is analyzed, and the guidance loop reflecting different internal dynamics structure and the model of disturbance rejection rate parasitic loop are established. The effects of time-to-go, different internal dynamics and time delay of seeker on the stability region of disturbance rejection rate parasitic loop are studied. Based on dimensionless adjoint function method, the effects of disturbance rejection rate and different internal dynamics on the proportional guidance system are also studied. The results show that the positive feedback stability region of disturbance rejection rate parasitic loop is affected by time-to-go, and the negative feedback stability region is affected by internal dynamics. The stability of parasitic loop caused by phase lag is mainly affected by the time delay of seeker. The effect of disturbance rejection rate positive feedback on proportional guidance system is more significant than that of the negative feedback. Miss distance increases with the increase in disturbance rejection rate. The internal dynamics structure of guidance system affects the guidance precision.
