靶场钻地弹爆炸位置的探测
Location of a blasted penetrator in the test range
摘要
Abstract
Aiming at the problem of locating a blasted penetrator in the test range,a method based on the changed detection technology is proposed.First,four synchronized geophones and a reused explosive source are used to record the stress waves twice,i.e.,before the penetrator fire and after the fire.By deducting inherent steep reflections,the reflected signal resulting from the penetrator blasting cavity is obtained as the change in the stress waves,which could be used for locating the blasted penetrator in the test range.Then, the ellipsoid equation focusing on each geophone and the explosive source are uniquely determined based on the wave path.Finally,an improved Chan algorithm is used to solve the intersection point of the ellipsoid models,and the estimated position of the blasted penetrator.This approach is verified by simulation.This method has a certain guidance in practical measurement of a penetrator in the test range.关键词
