基于声传感器阵列的海洋环境目标定位是水下信息处理的重要研究内容之一。针对传统水声定位系统难以保证传感器阵列满足所需的特定几何形状的问题，提出了任意阵型的四元声传感器定位方法。该方法放松了对阵列布放的几何结构要求，盲区相对较小，具有较好的工程应用前景。通过典型阵型(矩形阵)仿真分析了时延估计误差对定位的影响，结果表明，该定位方法可以实现水下目标的三维定位，并具有较高的定位精度，可应用于水下战场声目标的侦查。

In marine environment,target localization based on acoustic sensor array is one of the important con-tent in the research of underwater information processing.In view of the traditional underwater acoustic positio-ning system is difficult to guarantee the sensor array to meet the required specific geometry,a new positioning method with arbitrary four-element array was put forward.This method is effective to solve the requirement of specific geometry and has a good engineering application prospect.The simulation results showed that the posi-tioning method could achieve three-dimensional positioning easily for underwater target and had a high positio-ning accuracy,it could be used in reconnaissance of battlefield acoustic target.
