Abstract:In order to achieve cooperative attack of multiple missiles, the impact time and impact angle control guidance-law with field-of-view limit was proposed. A new impact time and impact angle control guidance-law was derived by adding two biases to proportional navigation, and the stability is analyzed by the Lyapunov theory. The guidance process with seeker field-of-view limit was designed by dividing angle control bias term into three stages for the reason that the seeker look angle may overstep the field-of-view and lose the target. Simulation results show that the seeker look angle is limited within the view field of the seeker and multiple missiles at different positions attack the target at a specific angle at the same time, achieving the cooperative attack effect under the designed guidance-law.
