摘要
为提高舰船目标识别率,采用小波多分辨率分析法对舰船辐射噪声进行多尺度调制谱和噪声谱特征提取及融合研究。并用提取的特征对三类舰船目标辐射噪声进行了分类识别实验,结果表明所提特征具有很好的分类识别效果。
Feature extraction on frequency-domain of ship radiated-noise is a key technique for ship-targets recognition.To improve recognition-rate of ship-targets,feature extraction on frequency-domain is studied by using the multiresolution analysis, and fusion of multiscale features on frequency-domain is discussed. The classification recognition for three different classes of ship-targets is measured,and the results show that the extracted features have better classification-effect.
