摘要：Interceptor guidance strategies are crucial in efficiently achieving desired terminal objectives. In this paper, a guidance strategy is proposed for interception of targets at pre-specified impact angle within finite time, by an interceptor in three dimensional space. The impact angle is defined as the azimuth and elevation of line-of-sight in the inertia reference frame, at interception. A suboptimal nonlinear guidance law is derived using the finite-time state dependent Riccati equation technique, for coupled engagement dynamics. The performance of the proposed guidance is tested for stationary and constant velocity targets using numerical simulations.
