دانلود Improvement of guidance law for simultaneous attack

Abstract

In  this  paper,  the  method  for  deriving  the  optimal  time-to-go  for  simultaneous  attack  and  how  to  guide  the missiles to impact the target at a designated time are proposed. The optimal time-to-go is obtained easily by considering the  homothetic  property  of  optimal  trajectories,  and  the  missiles  participating  in  simultaneous  attack  are  guided suboptimally to satisfy the final time constraint by applying one of the optimal guidance laws. Simulation results show that proposed method achieves a simultaneous attack with less control effort than other cooperative homing method.
