针对靶场钻地弹爆炸位置探测的问题，提出了一种基于变化检测的位置探测方法。首先，利用可重复触发的爆炸源和4个同步地震检波器对靶场地下应力波进行检测，通过比较打弹实验前后应力波的变化扣除地层背景干扰，获得钻地弹爆炸腔的反射信号。然后，根据波程建立以爆炸源和地震检波器为焦点的4个椭球面方程。最后，利用改进的Chan算法估计出椭球模型的交点，亦即钻地弹爆炸腔位置。仿真实验验证了此方法的可行性。该方法对靶场钻地弹实验测试具有一定的指导性。

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.
