【摘要】：為了增加水下高速目標(biāo)的識(shí)別特征維度,優(yōu)化識(shí)別效果,該文設(shè)計(jì)了一種基于目標(biāo)輻射噪聲高速特征量(High Speed Characteristic Quantity,HSCQ)的分類方法。首先,針對(duì)水下高速目標(biāo)輻射噪聲的DEMON(Detection of Envelope Modulation On Noise)譜特征進(jìn)行分析,根據(jù)DEMON譜的頻率可分性,定義了DEMON譜調(diào)制分布比(Modulation Distribution Ratio,MDR)。然后,根據(jù)水下高速目標(biāo)輻射噪聲的功率譜歷程圖直紋特征,應(yīng)用圖像邊緣檢測(cè)、線譜生長(zhǎng)等理論進(jìn)行特征提取,并分析了功率譜歷程圖的直紋特征量(Straight-line Characteristic Quantity of Spectrum,SCQS)。最后,根據(jù)2種特征量的實(shí)測(cè)信號(hào)分析結(jié)果,定義了目標(biāo)輻射噪聲的HSCQ,實(shí)現(xiàn)了一種新的水下高速目標(biāo)分類方法。實(shí)測(cè)信號(hào)分析結(jié)果顯示,采用MDR或SCQS進(jìn)行單特征量分類,非高速目標(biāo)的誤報(bào)率分別為21.4%和16.3%;采用HSCQ進(jìn)行分類,非高速目標(biāo)的誤報(bào)率僅為4.1%。
[Abstract]:In order to increase the recognition speed characteristic dimension of underwater target recognition, optimization effect, this paper based on the design of a high speed target radiated noise characteristics (High Speed Characteristic Quantity, HSCQ) classification method. Firstly, aiming at the high speed underwater target radiation noise of DEMON (Detection of Envelope Modulation On Noise) spectral features were analyzed. According to the frequency of separability DEMON spectrum, DEMON spectrum modulation distribution than the definition (Modulation Distribution Ratio, MDR). Then, according to the power of high-speed underwater target radiated noise spectrum of straight line features, application of image edge detection, line growth theory for feature extraction, and analyzes the characteristics of ruled power spectrum Graphof (the Straight-line Characteristic Quantity of Spectrum, SCQS). Finally, according to the measured signal of the 2 eigenvalue analysis results, the definition of the target radiation noise of HSCQ implementation A new classification method for underwater high-speed targets is presented. The measured signal analysis results show that the false alarm rates of non high speed targets are 21.4% and 16.3% respectively by using MDR or SCQS, and the false positive rate of non high-speed targets is only 4.1%. when classified by HSCQ.
