The Anti-ship Missile Terminal Guidance Radar Jamming Technology Research

In modern naval warfare, the most threatening for the surface ship, especially big,medium-sized ships, is anti-ship missiles. In Taiwan, active-commissioned anti-shipmissiles are mainly “Harpoon” anti-ship missiles from America and self-research“Hsiung-Feng” II anti-ship missiles from Taiwan. In this situation, this paper willresearch into “Harpoon” and “Hsiung-Feng” II anti-ship missiles and jammingtechnologies to them and simulation evaluation.The anti-ship missile from launch to hitting the target mainly undergoes threestages: the stage of the initial guidance, the stage of the middle guidance, the stage ofthe terminal guidance. Among them, the initial guidance and the middle guidanceoften adopted in the combination guidance with inertial guidance and GPS, Jammingto the anti-ship missile in the both stages is difficult. Therefore, this paper focuses onthe study of jamming to the stage of the terminal guidance of “Harpoon” and“Hsiung-Feng” II anti-ship missile.In the stage of the terminal guidance, the anti-ship missile mainly relies onguidance information provided by the missile seeker to track targets. Jamminganti-ship missiles in the stage of the terminal guidance is actually jamming the missileseeker. However, through several generations, guidance mode of the missile seekerdevelops from a single guidance mode to multimode composite guidance. Now, theanti-ship missile has increasing missile accuracy, faster, more and more powerfulanti-jamming ability. In view of the working principle and the anti-interferencecharacteristics of the missile seeker in both “Harpoon” and “Hsiung-Feng” II anti-shipmissile, this article puts forward corresponding jamming and jams to them anddesigns simulation evaluation.First of all, this paper will study the guidance raw of the anti-ship missileterminal guidance radar; summarize and analyze the jamming measure againstanti-ship missiles of modern ships. Second, this paper will research into the workingprinciple and the anti-interference characteristics of the missile seeker in both“Harpoon” and “Hsiung-Feng” II anti-ship missile, increasing attack process of“Harpoon” anti-ship missile, the terminal guidance radar performance, the modelingof the terminal guidance radar and the anti-jamming ability of “Harpoon” anti-ship missile; imaging system modeling and signal processing modeling of the infraredimaging guidance seeker in “Hsiung-Feng” II anti-ship missile, the working principleand the anti-interference characteristics of “Hsiung-Feng” II anti-ship missileguidance seeker with dual mode(active radar/infrared imaging). Third, in view ofanti-interference characteristics of both “Harpoon” and “Hsiung-Feng” II anti-shipmissile, this paper will present complex use of both ship-board electronic jammingandoutboard active decoy against “Harpoon” anti-ship missile and complex use ofboth outboard active decoy and surface-type infrared decoy against “Hsiung-Feng” IIanti-ship missile and design simulation evaluation. And that the simulation results areanalyzed explain such jamming measure is effective. Finally, the main work of thefull text is summarized, the problems to be solved are pointed out and the next stepresearch work is expected.
