In attacking the ships in coral island or reef area, there exist the disadvantages of complicated background and obstacles.Combination attack using multi-type Anti-Ship Missiles (ASMs) with different flight velocities, different trajectories and different guidance modes in multiple directions can improve the attack effect.Based on the influence of islands to missile path and target acquisition of radar seeker, and the angle required between adjacent missiles, an attacking angle coordination model is built up for coordinated attack of multi-type ASMs from multi-platform in attacking ships in coral island or reef area.The example shows that the model established can be taken as a theoretical reference for selecting reasonable angles for each missile.
