Cooperative Robust Line-of-Sight Guidance Law for Aerial Target Defense

We consider a three-body conflict problem in which an aerial target is pursued by a homing missile, and the target launches a defense missile to intercept the homing missile. Under the assumption that the homing missile adopts a proportional guidance law with more maneuverability than aerial target and defense missile, we propose a cooperative robust line of sight guidance law based on a nonlinear control method. Simulations are carried out for the different levels of cooperation and compared with the traditional proportional guidance law, showing the better performance of proposed guidance law.
