[0002] With the application of electro-optical technology, information technology, control technology, and microelectronic technology, many new guided munitions have emerged. They are very different from traditional munitions in terms of action principle, flight principle and ballistic characteristics, which promotes the development of new external ballistics. The establishment and development of the theory, inevitably, its structure and parameters will be more complex

[0003] In recent years, various countries have vigorously developed high-precision and low-cost new guided munitions. At present, the parameters of the outer ballistic structure of the uncontrolled section, the middle guidance section, and the final guidance section are mainly selected through digital simulation. However, this method is only suitable for simple structures. There are few traditional guidance methods, but it is difficult to determine the structure and parameters with high reliability for the new middle and terminal guidance laws, and it is impossible to carry out live ammunition flight tests with high cost and long period, which hinders the development of new external ballistic theory and Its application in new guided munitions
