Warhead Fragments' Distribution Measurement Method by a Multiscreen Sensors' Intersection Test Mechanism and Equivalent Target Damage Probability Calculation

To scientifically evaluate the damage effectiveness of a projectile explosion on the equivalent target, this article studies a warhead fragment distribution parameters' measurement method based on a six-screen-sensors' intersection test system; establishes a parameter calculation model of the warhead fragment hitting the equivalent target, the time and space constraints' discriminant model of six infrared detection screens, and the time-value-matching model of multiple warhead fragments; and gives the calculation of the specific fragment distribution position and the time-matching algorithm of each infrared detection screen. According to the obtained warhead fragment parameters, a calculation method of the damage probability of equivalent target is constructed. Through experiments and analysis, it is verified that the established warhead fragment parameter measurement method and the damage probability model of the equivalent target are scientific.
