Air-to-air Missile Over The Shoulder Fired Guided Research

"Over the shoulder" (OTS) is a new attack mode, in which ownplane uses airborne fire control system to launch and control air to air missile and attack rear targets. This will improve the ownplane's ability in air fight without question. OTS has two launch modes: forward firing and rear firing, i.e., the ownplane can launch missile forward to attack rear targets or launch missile backward to attack rear targets. Forward firing is discussed in this article only.Three contributions are made in this article:1. Design of OTS's middle guidance law. Since OTS is in which ownplane launches air to air missile forward, then the missile come back and fly over the ownplane to attack rear target. This will augment the off-sighted angle before the launching of missile. In this article, proportional guidance and optimization control theory are used to discuss the middle guidance law, and simulation results are provided and analyzed. After simulating, several effects on the guidance law are found which consist of missile and target's maneuverability and missile and target's prepositive angle.2. Design of OTS's attitude control system. If the interceptor's roll angle is zeroed, such a complicated system can be viewed as a combination of three simple subsystems. In each subsystem, variable structure controller, PID controller and an integrated controller of PID and variable structure controller are designed to make the subsystem robust to disturbances. Simulation results illustrate the effectiveness of the integrated control.
