Interceptor Guidance and Control

← All Research Areas

Overview

Interceptor guidance is concerned with designing guidance laws that steer a missile or interceptor to hit a target while satisfying terminal constraints such as impact time, impact angle, or both simultaneously. These constraints are critical in salvo attacks, cooperative interception, and angle-constrained scenarios.

My research develops exact-time convergent guidance strategies that achieve desired impact conditions against both stationary and moving targets. The work also addresses input constraints, asymmetric bounds, and integrated guidance and control (IGC) formulations that couple the guidance and autopilot design.

Key Contributions

  • Exact-time convergent impact time guidance against moving targets.

  • Impact angle and input constrained guidance against stationary targets.

  • Integrated guidance and control for impact-time-constrained interception.

  • True-proportional navigation based exact-time impact time guidance.

  • Asymmetric input constrained range-to-go based impact time guidance.
