Considering that the terminal impact angle constraint can improve the interception performance of hypersonic target, a novel particle swarm optimization guidance (NPSOG) algorithm is proposed to satisfy the impact angle constraint.Two-dimensional dynamics engagement mode for hypersonic target interception is formulated.The performance index is posi
