Models of time coordination for shipborne weapons common-frame launch

Abstract

Common-frame launched weapons must be coordinated in airspace and time for ensuring safety of ship and weapons. This paper researches with emphasis on the problem of time coordination. Firstly, the process of common-frame launch is analyzed and a common model of launch sequence of weapons is advanced. Secondly, factors considered for time coordination are studied including launch rate, influence on adjacent cells, influence of initial trajectory intersection and launch priority. Lastly, model of launch time spacing and model of launch priority are advanced, which make up of models of time coordination. The results show that models of time coordination answer the question that when is appropriate to launch missile or deliver authorization for the issuance of ignition commands to missile for avoiding the time collision between missiles launched simultaneously.
