Maritime application of ducted-fan flight array system: decoy for anti-ship missile

Abstract

This paper proposes a decoy application using a ducted-fan flight array system which composes of multiple single modules. Each single module has a conventional ducted-fan configuration and can fly individually. For the single module and the connected array, kinematic and dynamic models are briefly introduced. Based on the derived models, a control system is built into a hierarchical structure based on the SMC and PID methods. Also, simple kinematics is applied for multiple ASM and a target ship. A PNG law is designed for the guided missile system. Furthermore, a sequential logic proposed to take account of an expected signal power (ESP) for the deployment strategy. The ESP is calculated using seeker and decoy signal models at a control station, and then the station sends path planning commands to the multiple decoys. A numerical simulation is conducted under the visualization environment and verifies the decoy mission with two missiles and two decoys. The simulation shows that the separated single modules fulfill the role of the decoy effectively to counteract the multiple ASMs.
