Research On Separation Of Missile And Submarine Errors In Submarine-Launched Ballistic Missile

The technology on separation of Missile and Submarine Errors (MSE) is the key issue of test and accuracy evaluation of Submarine-Launched Ballistic Missile (SLBM). It is systematically lucubrated in this dissertation. Beginning from constructing the MSE transmission model, available separation methods of MSE are investigated, and then feasible separation projects of MSE are designed and realized based on them. Furthermore, many factors'effects on separation of MSE are analyzed, and a Missile Experiment scheme with optimization design is validated at the end.Firstly, noticed that MSE contains Guidance Instrumentation Error and Initial Error, its transmission model constituted and validated, based on constructing the mentioned two ones'transmission models. Secondly, some linear estimation methods are discussed, refer to the experience of separation of Guidance Instrumentation Error. Then, on the one hand, MSE is separated using main-component method, one of them. On the other hand, a new method called trajectory recurrence method based on Evolution Strategy is proposed and studied from many aspects, whereas Evolution Strategies have excellent performance and correspond to the issue. The performance of this method is evidently more excellent than main-component method, so feasible separation projects of MSE are designed and realized based on it. Thirdly, for many other factors correlate with the separation of MSE, their effects on it are analyzed. Lastly, a Missile Experiment scheme which is optimally designed is introduced. During its designing, NN modeling method based on Uniform Design is used. And its design focuses on the trajectory design and the orientation of INS. Its validity of separation of MSE is mainly validated, in this study.The goal of this dissertation is to supply technological sustainment for test and accuracy evaluation of SLBM and scientific gist for reducing Circular Error Probable (CEP) of it.
