Simulation study on defense process of space targets

A ballistic missile is one of the main targets of space target defense and often has an established trajectory. As the target, we are only interested in its trajectory. The intercepting missile, as a defense body, controls itself toward the target according to the target state observed information and the control strategies in real time. So, the kinematic equations, the dynamic equations and the control equations of the intercepting missile based on “transient equilibrium” hypotheses are more studied in detailed. In order to attack the target with the proportional guidance law in a three dimensional space, the dynamic equations of the proportional guidance law are established in two orthogonal planes which are projected onto by the motions of the missile and the target in the space. In the simulation phase, a distributed computer simulation system is established and the entire defense process is achieved in real time.
