In the context of modern warfare, traditional guidance laws aimed at indirectly intercepting or collide the target are not effective in destroying strategic targets. In this paper, a novel three-dimensional guidance law is proposed based on the sliding mode control with impact angle constraints, which guarantees the missile to intercept the target at a desired angle. In order to meet the realities of combat, the guidance law is based on finite time convergence. The singularity issue of the guidance law is theoretically analysed for the missile to intercept the manoeuvring target with any impact angle. The stability is also analysed by Lyapunov theory, which ensures that the guidance law can converge to zero in finite time. Simulation results demonstrate the proposed approach effectively and robustly intercepts the target with impact angle constrained.
