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.
