中文摘要:
      瞬态回波在水下目标探测方面具有比稳态回波频谱宽、反隐身性能好的优点。本文研究了利用小波变换提取水下目标瞬态回波的边缘特征并进行目标分类的可行性。对试验数据处理的结果表明,该方法有一定研究价值。
英文摘要:
      Comparing with the steady echoes, transient echoes have the advantages of broadband and capability of anti-hidden body in underwater targets recognition. The feasibilities of using wavelet transform to extract the edges of the echoes and then classify the targets based on the edge features have been studied in this paper. Study on a group of test data shows that this method has potential research values.
