Three Dimensional Optimal Guidance Law for Micro Missiles to Attack Maneuvering Targets

Abstract

In order to adapt to the developmental trend of micro missiles, three-dimensional optimal guidance law design for air-launched micro missiles to attack ground armed vehicles. Relative motion equations of micro missile and target are established. The performance index function is designed to reach undershoot quantity least and overload did not exceed a certain value. The optimal guidance equations are detailed derived in the three-dimensional space. We did the simulation which optimal and proportional guidance law are adopted for micro missiles to attack ground maneuvering armed vehicles. The simulation results illustrate that the optimal guidance law compared to the proportional guidance law has following advantages: high precision-guided and low overload characteristics.
