Sub-warhead Impact Point Sampling Simulation Under Ellipse Ring Dispersion

Considering diverse dispersion characteristics of sub-warhead in accordance with the existing documents, the property of ellipse ring dispersion was specific by sub-warhead trajectory simulation. According to this specific property, adopting three kinds of sampling methods, such as rectangle, bound and reverse-transform etc, to get sub-warhead impact point sampling formula under ellipse ring dispersion. By Pearson uniformity test, the good uniformity of simulation impact point was found. Taking trajectory simulation result as the standard, more real simulation result was got when adopting ellipse ring dispersion in sub-warhead impact point dispersion simulation.
