Abstract

A polynomial based guidance law dependent on range-to-go, is proposed for interception of a stationary target by a dual-seeker interceptor. The guidance law governs a desired look angle profile as a cubic polynomial of the range-to-go. The coefficients of the polynomial are obtained by satisfying the boundary conditions on the look-angle at the launch and impact points as well as imposing the respective field-of-view constraints of the seekers during the individual phases of their operation. The proposed guidance law also achieves reducing acceleration demand in the terminal phase of the interceptor trajectory. Simulation results show the efficacy of the guidance law.
