地波探测炮弹落炸点坐标研究

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。

Coordinate Research on Shell Fall-Explosion Points Detected by Land Wave

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 i...
