Design of Guidance Law at Coasting Path for Short-range Surface to Surface Tactical Ballistic Missile

The guidance law at unpowered phase for short range surface to surface tactical ballistic missile with cluster warhead and overall system inertial guidance program is studied. To obtain closed form solution, by applying the virtual object, the optimal control problem is transformed to problem which finds optimal guidance law for the missile to intercept virtual object, then the guidance law at unpowered phase is finded. Simulation results show that the guidance law has high anti jamming ability, high accuracy and low acceleration saturation within the specifications.
