摘要: It is of the essence for passive homing interceptors to acquire information required implement guidance laws. In practical applications, accuracy obtained directly exerts an influence on terminal performance. order achieve hit-to-kill, a modified three-dimensional proportional law designed enhance observability presented in this paper. The dynamic model interception based Singer and observation equation infrared seeker are established. A real-time two-step estimator adopted estimate states used realize law, solving problem application law. Simulation results indicate that cascade with produces small miss distance, satisfying requirement interception.
