Abstract

The paper deals with the possibility of direction finding and determining the coordinates of a source of acoustic signal emitted by a surface or underwater vehicle in the subsonic frequency range. For this purpose combined hydroacoustic receivers are used. During the first experiment, the estimates of the systematic component of direction finding error were obtained when the source emitted a tone or polyharmonic signal, and the direction finding results were averaged over a set of frequencies. The obtained results were used in the second experiment for estimating the error in determining the coordinates of the polyharmonic signal emitter consisting of three combined receivers (CR) which form the navigation base distributed in the horizontal plane.

组合水声接收器测向与确定信号源坐标的误差估计

摘要

本文讨论了在亚音速频率范围内寻找方向并确定水面或水下航行器发出的声信号源坐标的可能性。为此,使用了组合的水声接收器。在第一个实验中,当信号源发出音调或多谐波信号时,将获得测向误差系统成分的估计值,并将测向结果在一组频率上取平均。将获得的结果用于第二个实验,以估算确定由三个组合接收器(CR)组成的多谐信号发射器的坐标时的误差,该三个组合接收器形成分布在水平面中的导航基础。
