中文摘要:
      针对DEMON谱调制频率的可分性进行研究。利用高速目标与非高速目标在调制频率成分上的差异性,对目标DEMON谱历程矩阵进行梯度差分和量化处理,定义了目标辐射噪声的量化矩阵和调制统计量,提出了一种基于目标辐射噪声调制统计量的水下高速目标分类识别算法,比较了不同门限情况下高速目标与非高速目标随调制统计量的分布情况。大量实测数据分析表明,此算法可以可靠地对高速目标进行分类识别。
英文摘要:
      Research on the separability of modulation frequency of DEMON spectrum has been done. Considering the difference between high and non-high speed targets in the modulation frequency components, the quantitative processing and the gradient difference of the DEMON process matrix are conducted, and the quantization matrix and the modulation statistics of target radiated noise are defined. A method based on the modulation statistics of target radiated noise is put forward to classify the high speed underwater targets. The modulation statistics histograms of high and non-high speed targets with different thresholds are compared. The method, which classifies the high speed targets well, is verified by experimental results.
