Research on the Time-Cooperative Guidance Against Stationary Target

A new time-cooperative guidance law against a stationary target, which can be applied to simultaneous attack of anti-ship aircraft using the influence angle constraint, is presented in this paper. Firstly, linearize the nonlinear motion equations of aircraft, based on several constraints. Secondly, the topology using guidance principles of the leader and followers are introduced. The introduced guidance principle of the leader consists of three terms, so that zero error distance comes true and terminal impact angle constraint is achieved. The guidance law of the follower has an additional time-to-go cooperative term to adjust its actual impact time to be the same with the leader’s. Thirdly, closed-form trajectory methods,which can prove that the zero error distance and expected impact angle performance of all movings can be realized. Results through lots of simulation certify the potency of the guidance law.
