| 1. | The operation codenamed " crowbeak " was mounted in a bid to eradiate the illegal soccer betting activities 该项代号戈壁的行动,旨在打击非法赌波活动。 |
| 2. | It is the key whether if can be made use of in the field of eradiate noise recognition efficiently 这样,本系统就融合了目标在不同方面的特征,为下一步正确的分类提供了坚实的基础。 |
| 3. | The operation codenamed " crowbeak " was mounted in a bid to eradiate the illegal soccer betting activities during the period of the european national - team competition 警方在欧洲国家杯比赛期间,展开代号戈壁的行动,以打击非法赌波活动。 |
| 4. | Usage : manufacture tungsten wire , frame of grid , elicit wire , bracket , unsag tungsten wire , mould rods in high temperature , eradiate cathode , electrodes , bracket of heating 用途:用于制造钨丝栅极边杆引出线支架不下垂钨丝,高温定型杆发射阴极电极加热子支撑杆等。 |
| 5. | Eradiate noise recognition obtains feature information of movement under - water target , which is produced by passivity sonar , and then decides its category by referring to a priori knowledge 本文的研究方法是从目标产生的辐射噪声中提取出目标的特征信息,结合已有的先验知识,对目标的类别做出判断。 |
| 6. | Above all , the system fuse the eradiate noise ' s different sides " feature and offer strong elements for the next process : classifying . it is very important to study the classifier in this dissertation 其中线谱特征反映了船舶辐射噪声的频域信息,能量特征综合了不同频段内的信息,而分维特征反映了信号的时域的信息。 |
| 7. | At last , i conclude a way to increase the recognition ratio of the under - water target . the method of this dissertation is to distinguish the property of the under - water target by eradiate noise 主要的工作是在前期研究的基础上,利用已有水中目标的特征提取和识别方法,应用人工神经网络技术,总结出一种水下目标识别方法。 |
| 8. | The dissertation tries to combine signal processing and information fusion with the application background of under - water recognition so as to improve the reliability and accuracy of eradiate noise recognition system 本文试图把现代信号处理技术与信息融合技术相结合,应用到具体的水下目标识别领域,以提高水下目标被动识别系统的准确性和可靠性。 |
| 9. | The process of feature extraction is to transform the eradiate noise signal to different feature space and extract the feature vectors that reflect the category of the input sample . the extracted features are the input modes to the classifier 特征提取的过程是把输入的船舶辐射噪声信号变换到不同的特征空间,提取出反映样本的类别特性的特征向量,并把其作为分类器的输入模式。 |
| 10. | Through the inspecting , the author selected three methods of eradiate noise ' s feature extraction . the methods include the pedigree , e - filter , fractal . in those methods , the pedigree is based on frequency field , the e - filter is based on the energy field and the fractal is based on time field 本文作者经过考察,采用了三种前期研究中较为有效的水下目标特征提取方法? ?基于功率谱估计的线谱特征提取方法、基于小波分析的不同频段内能量特征提取方法和基于水声信号分维特性的特征提取方法。 |
