摘　　要：水下爆炸试验中,对爆源的定位具有重要意义。本文通过对比分析应用于水下爆源定位测量的各种技术手段,总结其特点和应用条件;针对水下爆炸试验的具体要求,提出适用于悬浮爆源的长基线水声定位测量方法;介绍长基线水声定位的原理,并给出定位计算的爆源坐标显式解。经过对水声定位测量方案的仿真计算和海上试验考核验证,对悬浮爆源的水平定位误差小于2.5m,指标满足水下爆炸试验对爆源定位精度的要求。It＇s important to position the explosive source in underwater explosion experiment. In the paper, first the technological means used in explosive source positioning and measuring were analyzed, and respective features and application conditions were summarized. Second aimed at specification in explosion experiments, LBL underwater acoustic positioning and measuring method applied to suspending explosive source was put forward. Then underwater acoustic positioning principle was introduced, and explicit solution of explosive source coordinates was given in locating calculation. Finally, underwater acoustic positioning and measuring scheme was simulating calculated and checked by sea experiment. Location error for suspending explosive source would be less than 2.5 meters. The parameters could fulfill the location accuracy for explosion tests.
