摘　　要：根据目前炮兵声测系统存在定位精度低且比较笨重等突出问题,提出了一种利用声传感器阵测量时延定位的新系统,以适应作战需求。着重建立了测量时延的五元阵模型,并与传统的四元十字阵模型进行了比较,分析比较了两种模型的定位精度,及采用五元阵定位的精度优势,五元立体阵定向性能优于四元十字阵,克服了四元十字阵由方位角不确定度引起的系统误差。所设计的定位模型定位精度高,满足了定位精度的要求。Aimed at the outstanding problems such as low location accuracy, heavy volume of the artillery acoustic survey system at present, a new type of acoustic survey system based on acoustic sensor array was proposed in order to meet operational demands. Five-element acoustic array model was set up and compared with traditional four-element cross array model. Location precision of two models were analyzed and compared, and the precision superiority of five-element acoustic array location was described. The conclusion is that the precision of five-element acoustic array is higher than that of four-element cross array, and the systematic error resulted from uncertainty of four-element cross array was overcome. Location precision of the model developed in the research is high and it can be satisfied with the requirments of location accuracy.
