Abstract

The invention belongs to the technical field of missile defense, and particularly relates to a remote interception launch data acquisition method and system based on a single-sided launch table, and the method comprises the steps: constructing a remote interception missile pseudo-six-degree-of-freedom trajectory calculation model, and determining an interception region boundary of an interception missile according to the interception capability and conditions of the interception missile; obtaining the maximum negative attack angle of each trajectory according to the number of the intercepted trajectories and the boundary of the intercepted region of the intercepted projectiles; based on the average launching point and launching azimuth angle values and the maximum negative angle of attack of each trajectory, generating a general single-sided launching table of a fixed launching azimuth angle by using a trajectory calculation model; and according to the single-sided firing table and the target prediction trajectory, initial values of the firing data are obtained, correcting the initial values of the firing data through one-time Newton iteration, and accurate values of the firing data are obtained. The problems of remote interception missile data calculation with an uncertain launching point and the like are solved, the calculation amount is reduced, the stability and efficiency of calculation equipment are improved, the real-time requirement of remote interception missile launching data calculation can be met, and the invention has high engineering application value and prospect.

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...
