Aimed at the poor performance of guidance algorithms designed based on a linearized model in active defense under large leading angle deviation. both-way and one-way cooperative sliding mode guidance algorithms based on the smooth nonsingular terminal sliding mode for the defense missile are proposed. The relative kinematics and linearized models of the target. the active defense miss... https://www.bekindtopets.com/great-pick-Obsidian-ULU-w-Eagle-clearance/
