Simulation of the Dispersion of Reconnoitering and Evaluating Sub-missile's Falling Points

The Reconnoitering and Evaluating Sub-missile(RES) of submunition warhead is one of the important means for real-time reconnaissance and evaluation of missile attack.The dispersion of RES's falling points directly influences the quality of reconnaissance image and the accuracy and validity of damage evaluation.By adopting the theory and methods of dynamics modeling,the paper establishes a ballistic dynamics model of RES,laying emphasis on the ballistic dynamics model of imaging platform deceleration.By analyzing the influencing factors of the dispersion of RES's falling points,choosing two main influencing factors-thrown height and stochastic wind,applying the simulation platform to do simulation experiments and analyze the result using numerical simulation method,we draw out the relational curves between these influencing factors and the dispersion of RES's falling points and get some conclusions.This conclusion provides the scientific data for the manufacture of Reconnoitering and Evaluating Sub-missile's system and application in combat.
