Aiming at impoving the efficiency of the anti radar aircraft, we adopt the tracking method in our research on the guidance law of the aircraft. We first introduced the characteristics of anti radar aircraft and the diagram of its guidance system as shown in Fig.1. In section 2, based on the aerodynamic parameters and flight data of a certain type of airplane, we established a mathematic model for direct side force control and put forward a decoupling method for the direct side force control system. Then, with the tracking method, we study the guidance law of the aircraft. Eq.(11) gives the guidance law. Simulation results(Fig.2) show the advantages of the guidance system with tracking method (Fig.2b), which include quick response, precise hit, good wind resistance ability and good effect of damage.
