Computational Impact-Angle Guidance with Biased Proportional Navigation
1 : Roketsan Missiles
A trajectory-shaping technique for controlling the impact angle is presented, where the time-to-go information is not required. The objective is achieved by augmenting the proportional-navigation guidance command with bias addition. In the most basic case, the bias is constant, which means the target will be captured with the bias term still acting. The analytical formulation shows that the bias is embedded within an integral equation, which is why a numerical solution is needed. The computational guidance law that is herein proposed is feasible for online implementation. The performance is demonstrated with computer simulations.
