The Method of Underwater Target Recognition Based on LOFAR Spectrum

摘要:

基于LOFAR谱图的主成分分析法是目前用于对水下目标识别的重要方法之一,文中详细分析了该方法的基本原理和具体应用过程,并对潜艇辐射噪声的实测数据进行了仿真和分类试验,给出了仿真图和试验结果。结果表明,运用该方法对水下目标进行识别的识别率较高。

Abstract:

The PCA based on LOFAR spectrum is one of the most important methods that are used to recognize underwater target. In this paper, the basic principle and specific application process were had analyzed detailedly, then use the real measured noise was used to carry through simulation and classification test, and the simulation diagram and experimental results supplied, which suggested that this method was effective.
