5044 首先，从流量中提取碎片化数据并且还原网页源码，同时加入标准化处理来提高识别准确率； At first, fragmented data from the traffic was extracted, and the source code of the webpage was restored. Next, a standardized processing module was utilized to improve the accuracy.
5045 然后，将网页源码分块，利用相似度散列算法对每个网页源码分块计算散列值，得到网页源码的相似度散列值，同时引入海明距离来计算网页源码之间的相似性； Additionally, the source code of the webpage was divided into blocks, and the hash value of each block was calculated by the simhash al-gorithm. Therefore, the simhash value of the webpage source codes was obtained, and the similarity between the webpage source codes was calculated by the Hamming distance.
5046 最后，截取网页快照，提取其 SIFT 特征点，通过聚类分析和映射处理得到网页快照的感知散列值，通过感知散列值计算网页相似性。 The page snapshot was then taken and SIFT feature points were extracted. The perceptual hash value was obtained by clustering analysis and mapping processing. Finally, the similarityof webpages was calculated by the perceptual hash values.
5047 在真实流量下的实验表明，所提方法的准确率为 93.42%，召回率为 90.20%，F 值为 0.92，处理时延为 20 μs。 Experiments under real traffic show that the accuracy of themethod is 93.42%, the recall rate is 90.20%, the F value is 0.92, and the processing delay is 20 μs.
5048 通过所提方法，在高速网络流量下可以有效地检测恶意镜像网页。 Through the proposedmethod, malicious mirror website can be effectively detected in the high-speed network traffic environment.
5049 源雷达机动目标长时间相参积累过程中，目标的运动参数会引起距离徙动和多普勒徙动，导致回波信号能量分散和检测性能恶化。 During the long coherent integration time in passive radar, the motion parameters (such as high speed, ac-celeration and jerk motion, etc.) will bring about range migration (RM) and Doppler frequency migration (DFM), fur-ther deteriorate the integration performance.
5050 为实现含有第二加速度的变加速运动目标相参积累，提出了一种基于频域序列反转变换（FRT）和改进吕分布（MLVD）的相参积累算法。 To realize the coherent integration of maneuvering targets with jerk mo-tion, a method based on frequency reversing transform (FRT) and modified Lv's distribution (MLVD) calledFRT-MLVD was proposed to achieve the coherent integration and motion parameters estimation.
5051 首先，利用 FRT 去除信号的距离徙动，将回波能量积累至同一距离单元； More specifically, theFRT was firstly proposed to remove RM.
5052 然后，利用 MLVD 对该距离单元内的回波进行处理，估计出目标加速度和第二加速度； Then the MLVD was employed to estimate the acceleration and jerk para-meters.
5053 在补偿目标的加速度和第二加速度引起的多普勒徙动后，利用 Keystone 变换（KT）校正目标速度引起的线性徙动，实现距离和速度的估计。 After compensating the DFM induced by the acceleration and jerk motion, the residual RM was corrected andthe velocity and range was achieved via the KT operation.
