"虎鲸"超大型无人潜航器的目标强度特性研究
Research on target strength characteristics of the Orca extra-large unmanned underwater vehicle
摘要
Abstract
[Objective]To investigate the acoustic target strength(TS)characteristics of extra-large un-manned underwater vehicles(XLUUVs),this study conducts a systematic analysis of the TS characteristics of the Orca XLUUV in the 1-10 kHz frequency band.[Method]Based on the Orca model,the finite element method is applied to calculate its TS in the 1-3 kHz frequency band,while the planar element method is em-ployed for the 3-10 kHz band.The results are compared with those obtained from the Benchmark model.To provide a more comprehensive evaluation of unmanned underwater vehicle(UUV)stealth performance,the concept of angular detection probability is introduced.Additionally,a scaled model experiment is conducted in a water tank,and a correction method is proposed for the experimental TS measurements.[Results]The TS characteristics of the Orca model are first analyzed.Compared with the Benchmark model,the Orca model ex-hibits superior stealth performance in the azimuthal direction,along with additional advantages in the circum-ferential direction at higher frequencies effects that become more pronounced as frequency increases.For ex-perimental cases in which the distance between the hydrophone and transducer does not meet the far-field con-ditions,the measured TS values are corrected,yielding improved consistency with the simulation results.This validates the accuracy of the numerical simulation results.[Conclusion]The findings of this study provide a theoretical foundation for optimizing underwater detection systems and enhancing the stealth design of UUVs.关键词
