摘　　要：在一次靶场试验中 ,根据测到的弹头爆炸产生爆光和爆声的时间差进行定位计算 ,计算爆点到测点的距离和实测结果不一致。根据这一实际情况对常规弹头爆炸产生声波的机理进行研究 ,分析了常规弹头爆炸瞬间产生声波的过程 ,从而 ,得出所测到的爆声的声源不是点源 。In certain shooting range test position of explosion center is determined by distance difference measurement, and the distances are computed according to time difference between explosion light and sound while warhead is exploding. In a result, distance computed from measurement station to explosion center is not equal to practical measured distance unexpectedly. On the basis of practical condition, mechanism of producing sound wave of conventional warhead's explosion is researched in this paper firstly. Then process of producing sound wave while warhead is exploding instantaneously is analyzed. Finally we come to conclusion that source of heard explosion sound is not a zero source, but a ball one.
