Research Topic #3: Guidance and Control (G&C) & Optimization

Guidance and Control (G&C)

Unlike the interceptor, whose maneuverability comes from aerodynamic force, the guidance capability of a high-altitude interceptor usually depends on a limited energy source, such as a thruster and Divert and Attitude Control Systems (DACS). Moreover, as the multistage missile has multiple boosting and coasting phases, the applicability of the conventional guidance law is limited not only by this constraint but also by the significant velocity changes and limited maneuverability. Hence, it is necessary to design a guidance law that considers these characteristics. 

System Optimization

Smart Design (Derivative-free Optimization)

Successful design for complex systems requires integrated design optimization. Widely adopted derivative-based methods are not applicable for such design optimization. Integrated simulation-based design optimization via the cross-entropy method (CEM) shows strong potential in complex design optimization.

Optimal Deployment of Defense Resources

Optimal deployment or arrangement of defense systems is critical to maximize the survivability of protected assets. To this end, we first evaluate the effectiveness of single interceptor , i.e., Single Shot Kill Probability (SSKP), based on the characteristics of the defense system, such as engagement geometries and error models within the system. Build up on this estimation model, the survivability of protected assets according to launcher positions can be derived, and thus we can derive the optimal arrangement of defense resources. There are still a lot of research opportunities to extend the previous research by considering multi-layer defense systems and diversities of threats.
