Abstract

The invention belongs to the technical field of missile defense, and in particular relates to a method and system for obtaining elements of long-range interception and launching based on a single-sided shooting table, constructing a pseudo six-degree-of-freedom ballistic calculation model of a long-range interceptor, and determining the interceptor according to the interception capability and conditions of the interceptor The boundary of the interception area; the maximum negative angle of attack of each trajectory is obtained according to the number of intercepted trajectory and the boundary of the interception area of ​​the interceptor missile; based on the average launch point and launch azimuth value and the maximum negative angle of attack of each trajectory, the trajectory calculation model is used to generate a fixed launch azimuth The general single-sided shooting table of angle; according to the single-sided shooting table and the predicted trajectory of the target, the initial values ​​of the launching elements are obtained, and the initial values ​​of the launching elements are corrected by a Newton iteration to obtain the accurate values ​​of the launching elements. The invention solves the problems of element calculation of long-range interceptor bombs with uncertain launch points, reduces the amount of calculation, improves the stability and efficiency of computing equipment, and can meet the real-time requirements of element calculation of remote interceptor bombs, and has strong engineering application value and prospects .

Description

technical field [0001] The invention belongs to the technical field of missile defense, and in particular relates to a method and system for acquiring elements of long-range interception and launch based on a single-sided shooting table. Background technique [0002] There are usually two methods for the calculation of missile launch parameters: one is the shot table method, that is, the corresponding relationship between the three-dimensional space position in the interception area and the launch parameters is calculated in advance, and the shot table interpolation is used to read the launch data according to the predicted interception point. parameters; the other is the Newton iteration method, by establishing the functional relationship between the launch parameters and the predicted intercept point, using Newton iteration to calculate the deviation of the launch parameters and correcting the initial values, and gradually obtain accurate parameters . The advantage of the...
