Target damage calculation method based on burst point space position

Abstract

The invention provides a target damage calculation method based on burst point space position. The method includes: acquiring planar two-dimensional position coordinates and spatial three-dimensionalposition coordinates of a projectile burst point image; building a coordinate system, and determining direction angle and pitch angle of projectile target crossing; acquiring expression of the direction angle and the pitch angle of projectile target crossing in each coordinate system, and acquiring multiple projectile target crossing postures changing along with time by changing missing distance and missing direction; acquiring a projectile target crossing space-time correlation model based on projectile burst position space position; acquiring damage probability of a fragment field to a target. A target damage calculation method of a space burst point position which is comparatively abstract is provided on the basis of position of space burst point, and a scientific basis is provided fornovel target damage calculation.

Description

technical field [0001] The invention relates to the technical field of photoelectric testing, in particular to a target damage calculation method based on the spatial position of an explosion point. Background technique [0002] The research on projectile target damage by projectile fuze is an important part of current enemy-friend strategy and offensive and defensive combat readiness. Since the explosion point of projectile proximity fuze is closely related to the relative spatial position where the target meets, the effect of projectile proximity effect depends on the distance between the projectile and the target. The spatial relative position between them, the detonation within the effective space can only produce damage to the target, and the fuze effect of the projectile is completed by its internal mechanism to obtain the reflected energy of the target and start the detonation control mechanism. Relative to the destroyed target Therefore, the damage effectiveness of t...

Problems solved by technology

Due to the random, high-speed, and uncertain distribution of the explosion point, the existing test methods and calculation methods cannot meet the objective evaluation of the target damage effectiveness of the current projectile fuze explosion point
