Abstract

This paper introduces a novel varying-gain proportional navigation guidance (PNG) law for driving constantspeed missiles to achieve desired impact angles on stationary targets. The unique advantage of the proposed varying-gain PNG law lies in its ability to provide accurate, analytical time-to-go estimations across a broad feasible region, which facilitate the precise control of impact time. To show the significance of our new method, the proposed varying-gain PNG law is augmented with a biased feedback command to obtain an impact time and angle control guidance (ITACG) law. Numerical simulations, in comparison with existing methods, demonstrate that both the proposed varying-gain PNG and ITACG laws can achieve desired impact constraints while requiring less control effort, even under conditions of large initial heading errors and stringent impact angle constraints.
