22476 该文提出一种新的在太赫兹频段下基于 MIMO 弧形阵列的方位向成像算法，通过将 MIMO 弧形阵列等效转换为 MIMO 线阵，基于等效 MIMO 线阵引入 RMA 算法思路对弧形阵列方位向图像进行重建。 A new azimuth imaging algorithm based on the terahertz single frequency MIMO arc array is proposed in this paper. The MIMO arc array is transformed to the MIMO linear array equivalently, based on which the arc array azimuth image reconstruction is designed and realized by using the RMA algorithm.

22478 网络地址变换通过动态地改变或映射主机的网络地址，使得攻击者收集到的地址信息变得无效，然而对于扫描到主机即发起攻击的扫描攻击，网络地址变换的防御性能有所下降，很少有研究从理论上分析网络地址变换对不同扫描策略的扫描攻击的防御优势。 Network address shuffling invalidates the address information collected by the attacker with dynamically changing or remapping the host's network addresses, however, the defense performance of network address shuffling decreases when against scanning attacks which launch attacks at the same time of discovering targets, and few studies analyze theoretically different defense advantages of network address shuffling against scanning attacks of different scanning strategies.
22479 该文考虑均匀变换和非重复变换两种网络地址变换策略，给出不同扫描策略的扫描攻击在静态地址环境以及网络地址变换环境下的概率模型，概率模型分析了攻击者命中至少一台主机的概率以及攻击者命中主机的数量； In this paper, two strategies of network address shuffling are considered: uniform shuffling and non-repeat shuffling. It presents probabilistic models of scanning attacks in the static address and network address shuffling environments, which analyzes both the probability of the attacker hitting at least one host and the number of hosts hit by the attacker.
22480 通过理论计算两种网络地址变换策略相比于静态地址环境的防御优势。 Then, the defense advantages of both network address shuffling strategies are theoretically calculated and compared with the static address environment.
22481 分析结果表明对于可重复扫描攻击，两种网络地址变换策略相比于静态地址环境不具有防御优势； Analysis results indicate that both shuffling strategies have no defense advantages against repeatable scanning attack compared with the static address environment;
22482 对于非重复扫描攻击，均匀变换仅当主机数量较少时才具有概率优势，非重复变换仅当主机数量占地址空间比例较小时才具有较高的比例优势。 uniform shuffling has probability advantage against non-repeat scanning attack only when the hosts number is small, and non-repeat shuffling has significant ratio advantage only when the hosts number accounts for a small proportion in the network space size.
22483 在贝叶斯框架下的多目标跟踪算法中，总是假设杂波的先验信息是已知的。 In multi-target tracking algorithms under the Bayesian filtering framework, it is usually assumed that the priori knowledge of clutter is known.
22484 然而，实际应用中，杂波分布一般是未知的，假设的杂波分布往往与实际情况匹配度差，难以保证滤波精度。 However, in practice, the knowledge of clutter is usually unknown, and the assumption of clutter may not agree with the truth, resulting in the filtering precision declining.
