Miss distance algorithm of terminal ship-to-air missile based on vector operation

The effect of terminal ship-to-air missile intercepting maneuvering target at high speed is studied through the method of three-dimensional trajectory simulation based on vector operation. The three-dimensional vector equation of command acceleration is elicited according to TPN at first considering the seeker´s noises and the rudder´s overload limit. An algorithm of calculating miss distance caused by guidance blind distance is raised here. The anti-ship missile´s trajectory model of rising and diving at the end is set up on the base of analysis its characteristics. The trajectory of ship-to-air missile intercepting anti-ship missile and the miss distance under different circumstances are simulated in Matlab. Then requirements of the target´s maneuver and noises about ship-to-air missile´s capability are analyzed which offers a technical reference on evaluating the fighting effectiveness of missile and on taking consequent intercepting measures.
