摘　　要：本文着重研究正交离散子波变换在非相干雷达船目标特征抽取中的应用。采用现场实录的四类船目标雷达视频回波数据进行实验，结果表明本文提出的方法运算简便，所抽取的特征具有典型性，数据压缩能力强。基于子波域特征提出了一种新的显著态回波的检测方法。This paper concerns the application of orthogonal discrete wavelet transform in fea-ture extraction for incoherent radar ship target recognition based on the Daubechies’compactly sup ported wavelets.Experiinents are carried out for the proposed method with four kinds of practical radar ship target video-echo data and the results indicate that the method is simple and easy in com-putation and the extracted features are typical with high data compression. A new detection ap proach for odd video-echo of radar ship target is propose1too.
