Research on the Cooperative Attack of Multiple Guided Bombs

Abstract

In order to enhance the coordinated strike capability of multiple guided bombs attacking ground targets, this paper studies the time-consistent strike problem of multiple guided bombs on the ground targets. First, for the nonlinear motion model of the bomb and the target, under the assumption that the speed of the bomb is constant and the target is stationary, the problem of simultaneous strikes of multiple guided bombs on the ground target is transformed into the remaining flight time and the velocity deflection angle of the bomb under the second-order integrator model, and a cooperative guidance law is designed in the longitudinal plane to solve the time-consistent strike problem of multi-guided bombs without a leader. Furthermore, in order to ensure the accurate determination of the cooperation, the time-consistent strike problem of the dynamic change of the bomb speed is considered in the leader mode, and the velocity deflection angle is used to design the cooperative guidance law in the horizontal plane, combined with the proportional guidance law of the longitudinal plane, to ensure the consistency of followers and leaders. Finally, the backstepping method is used to generalize the design of the velocity deflection angle for consistency to the design of the vertical overload, and the low-pass filter is used to further reduce the computational complexity. The simulation results show that the cooperative guidance law can ensure that multiple guided bombs can strike the target almost simultaneously, which proves the effectiveness of the cooperative guidance law.
