Research and Simulation on Passive Sonar Target Locating Technology

介绍被动声呐浮标定位技术的原理和应用,分析研究不同浮标阵型对定位精度的影响及其阵型的选择方法,提出包含多种因素在内的定位误差数学模型。通过对不同浮标阵型的数学模型进行推导或对其定位误差进行模拟仿真得出:如采用三元阵,则三元对称阵定位误差最小;如采用四元阵,则四个浮标组成内角为60°和120°的菱形阵时,理论上定位误差最小;如采用多浮标随机分布阵型,浮标尽量均匀分布则误差较小,且在3、4、6、8个浮标情况下的平均定位误差仿真值分别为28.076 m、24.187 m、22.978 m、18.181 m,从而为被动声呐反潜技术的研究与应用提供参考。

The principle and application of passive sonar target locating technology is presented,the influence of different buoy formations on positioning accuracy and the selection method of formation discussed,the mathematical model of positioning error including many factors propose,and the mathematical model with different buoy formations also deduced.And simulation on its positioning error indicates that if the three-element array is adopted,the positioning error of the three element symmetrical array is minimum;if the four-element array adopted and when the four buoys form the diamond matrix with 60 degrees and 120 degrees interior angle,the theoretical positioning error is minimum;if multi-sonobuoy and random array adopted,the error would be minimum when the sonobuoy uniformly is spread.Under the circumstance of 3,4,6,8 sonobuoies,the average positioning error values would be 28.076 m,24.187 m,22.978 m and 18.181 m respectively,thus provides certain reference for the research and application of passive sonar antisubmarine technology.
