摘　　要：文章结合声阵列在智能雷系统中的应用,提出了用立体五元声阵列对声目标进行定位,将智能雷中用于预警的传感器也参与到定位阵列中来,这样就在不增加传感器的条件下实现了立体阵列对声目标的定位。文章推导了定位公式和误差公式,并对结果进行仿真分析,与平面阵相比取得了较好的效果。不但提高了精度还降低了声阵列的盲区。Associated with the application of acoustic array in a smart mine system this paper presents, for acoustic target localization, the use of a pyramid array consisting of five sensors. The method takes the sensor which is used for prewarning as a part of the location array, such that target location is achieved without increasing the number of sensors in the smart mine system. The paper deduces the location formulas and the fallibility formulas, and then by simulation shows that the method has a good performance compared with a plane array, not only improves location accuracy but also decreases the blind space.
