Abstract:
Missile guidance accuracy and terminal performance are critical in engagements against maneuvering or time-sensitive targets. Achieving both high terminal impact velocity and reduced time of flight is essential to enhance terminal homing effectiveness. This work proposes a two-stage midcourse guidance strategy: (i) offline optimization of Proportional Navigation Guidance (PNG) parameters to maximize terminal velocity across varying engagement geometries, and (ii) real-time intercept-point estimation combined with lookup-table retrieval of near-optimal PNG gains to adapt dynamically during flight. The proposed method is evaluated by comparing estimated and actual impact conditions, demonstrating improved response time, higher terminal velocity, and robust performance relative to conventional PNG approaches.
