摘要
本文主要论述对海上目标信号和海洋环境噪声的测量及其结果的分析。着重分析了目标信号及环境噪声的声级、信噪比、相关性和目标检测作用距离,为短基线系统被动定位系统的设计提供依据。
The measurement of object signals and ambient noise at sea, as well as the analysis of its results are described in this paper. Emphasis is put on the analysis of sound level, S/N ratio, correlation of the object signals and the ambient noise as well as on the distance of the object detection. The results of analysis provide fundation for system design of a short-base-line positioning system.
