摘　　要：对海面偶极子声场提出基于单个水听器的定位算法,并设计信号处理流程和双曲线提取的Hough变换法。海试结果表明信号处理和双曲线提取具有较高增益,定位算法稳健、具有较高精度。该算法所需设备简单,运算量小,在近距离目标运动参数估计和辐射噪声测量方面具有特色。Based on a single hydrophone in dipole sound field a positioning algorithm is presented, and the signal processing flow and Hough transform for hyperbola distilling are designed. It＇s proved by sea trials that the signal processing flow and hyperbola distilling have high processing gain, while the positioning algorithm is robust and accurate. This algorithm only needs simple equipments and is distinctive in radiating noise measurement and in parameter estimation of moving targets in short distance.
