Guidance law of bounded-control missile for attacking an aircraft with defending missile

To improve the kill probability of attacking missile for target aircraft interception while avoiding a defending missile, a guidance law for attacking missile is presented based on differential game theory. The differential game theory has natural advantages for game of multi-body with independent control. As compared to optimal guidance law, the differential game guidance law further takes into account of the bounded control of attacking missile and is adapted to the attacking missile, target aircraft and defending missile with high-order control dynamics. Nonlinear simulations are carried out to verify performance of the guidance law, and the results show that the attacking missile can intercept the target with near zero miss distance while avoiding the defending missile successfully. To fulfill the avoiding and intercepting mission, the attacking missile only needs two times maneuvering performance against the defending missile. © 2016, Editorial Department of Journal of Chinese Inertial Technology.
