Abstract


The anti-ship missile after four generations of development, become the main battle weapon to attack enemy surface ships. Modern naval center transferred to the offshore battlefield natural complex electromagnetic environment seeker's field of view may appear more objective, multi-target selection capability of the missile needs to be improved. Lack of operational missile target recognition capability, relay-guided lower level, difficult to adapt to the needs of offshore operations, a number of improvements must be based on the existing typical system. Precision inertial navigation system with independent data update rate, short-term, high precision, anti-interference ability and has been widely used in various types of anti-ship missiles. This article based on the existing system, the use of high-precision inertial navigation credible prior information, and set a reasonable target selection point and select the area, improve the performance of the missile target capture, has a practical significance to adapt to the complex environment of offshore operations. Is divided into five chapters, each chapter summarized as follows: the first chapter of the demand and the significance of the background of this study, system summary of the research status quo of high precision inertial navigation systems and anti-ship missile raids way, to elicit this article to be solved The core issue of research ideas. The second chapter analyzes the high-precision inertial navigation system. First, the summary of the course of development of the inertial navigation system, the existing levels and trends. Then established a mathematical model of the platform inertial navigation system, inertial navigation system error characteristics by simulation analysis. The subsequent information seeker and inertial navigation systems integration program - the Doppler velocimetry auxiliary platform inertial navigation precision inertial navigation missile concluded. The third chapter analyzes the anti-ship missile raids. First, an overview of the the manhunt way classification, existing institutional, improved innovation and development trends. Seeker search and then create a dynamic model of the gate, and target acquisition process simulation. Subsequently integrated the the controlled endpoint error target distribution and point shooting, proposed a new method to calculate the capture probability, a detailed analysis of the factors affecting the acquisition performance, and draw some useful conclusions. Finally, select Figure admission contrast and extended two commonly used manhunt way analysis, to lay the foundation for the subsequent proposed improvement strategies. Chapter hunt strategy based on precision inertial navigation. First, assume that the offshore typical combat scene, considering the self-control endpoint error and target distribution error, the credibility of the concept of inertial navigation information, and quantitative description of the inertial navigation system to provide credible target a priori information. Then, based on the the inertial navigation credibility proposed admission contrast style raids and extended the Select Figure manhunt improvement strategies: setting a reasonable choice points and establish a reasonable target selection. Chapter summary of the full text of the summarized paper work and innovation, discussed the direction of the follow-up study.
