Multiburst Location Optical Testing Method and Target Damage Efficiency Assessment Arithmetic

The target damage efficiency is a key content in weapon testing field to assess new weapon damage performance, this paper researches the projectile multiburst location optical testing method based on double area array camera and assessment arithmetic of target damage efficiency. The optical testing model of 3-D coordinate on the projectile multiburst location is set up using double area array camera. Based on the 3-D coordinates of projectile multiburst location and finite element analysis theory, the calculation method of target vulnerability area was researched and analyzed by dividing the target vulnerable area into many unit areas to develop assessment arithmetic of target damage efficiency. The relationship of fragments size, impact angle, and vulnerable surface unit area size and the calculation methods of the target vulnerable area and damage sensitivity were discussed. The target damage probability was also calculated and analyzed using projectile fragments distribution density, number of fragments, and fragment cloud scattering radius. Through the calculation and experiment, the result shows that the assessment of target damage efficiency is closely related to 3-D coordinates of the projectile multiburst location, fragments size and velocity, vulnerable surface unit area size, and effective number of fragments per unit area.
