Abstract:
Missiles with high speed and maneuverability utilize various guidance algorithms to reach their intended targets. While some algorithms are designed solely for target acquisition, these algorithms can be diversified based on desired impact angles or times. The Impact Vector Guidance (IVG) algorithm ensures a missile collides with a stationary or moving target at the desired angle. In this study, the objective is to preserve the impact angle performance of the existing IVG guidance law while adding impact time capabilities using Bézier curves and a virtual target approach. Bézier curves are mathematical curves generated using basis functions and control points to form parametric polynomials. Initially, virtual targets are created using Bézier curves, and the guidance law borrowed from the literature enables impact angle constraints while chasing the virtual target. Impact time selection is made possible through the use of virtual targets. Consequently, by integrating impact time constraints into IVG, successful strikes on stationary targets are achieved. The application of this newly obtained three-dimensional guidance law called Enhanced Impact Vector Guidance (EIVG) is presented for different scenarios.
