基于直达波与地声界面波时延的目标定位方法
|
摘要
有报道地震波技术在美、俄装备中已有应用,但因保密,未见公开发表文献。为了利用地声界面波的特性实现水中目标的探测,提出了利用地声界面波的传播特性进行水中目标探测的方法,该方法利用直达波与地声界面波的时延实现目标的被动定位。仿真计算表明,测得距离与实际距离非常接近。
It was reported that the seismic wave technology had been used in US and Russia military equipment,but there was no information in details.In order to detect underwater target,the propagation characteristics of geosound interface wave was applied to passive localization.The method was based on the delay inequality of scholte wave and direct wave.The basic idea of the passive localization method and the way of implementation were introduced.The numerical simulation illustrated that the method was feasible.
