Target Damage Distribution Probability Calculation Arithmetic Based on Space Tangential Differential Unit Area

The target damage probability is a key performance index in weapon damage efficiency evaluation, to acquire the target damage distribution probability, this paper researches multifragments location measurement method using multiscreens measurement method, and studies the target damage distribution probability calculation arithmetic based on space tangential differential unit area. The testing model of multifragments location is setup using the six-screens across principle and gives the calculation formula. According to the spatial location parameters of multifragments, the target damage distribution calculation model is setup by dividing the target space area into many space tangential differential unit areas. Based on the spatial distribution density of projectile multifragments, the target damage efficiency calculation principle and method of multifragments in the 3-D space is analyzed, the interaction extent function about multifragments and target unit area is deduced, and the calculation function of target damage distribution probability is given on the basis of spatial distribution range parameters of multifragments. Through the calculation and experiment, the target damage probability calculation arithmetic was validated, the results show the calculation method and arithmetic are correct.
