23925 该文提出一种在空时 2 维谱平面联合距离维逐空-时频点谱估计与滤波的协方差矩阵估计方法。该方法根据杂波和目标在距离-空时 2 维谱平面的分布特性，逐点频估计待检测单元杂波谱，并采用中值滤波方式消除目标污染对地物杂波谱估计的干扰； Thus, in this paper, the space-time spectrum of the clutter Cell Under Test (CUT) is estimated according to the distribution characteristics of the clutter and the moving target in the range and space-time two dimensional spectrum plane. In addition, the median filtering is exploited to avoid the disturbance due to the moving target for the estimation of clutter spectrum.
23926 最后重构无空时孔径损失的杂波协方差矩阵。 Finally, the reconstruction of clutter covariance matrix without sacrificing space-time aperture and clutter suppression is achieved．
23927 仿真结果表明，相比于传统非均匀统计STAP 方法，所提的距离-空时 2 维谱滤波方法能够在样本数不足时有效缓解目标信号污染、离散地形杂波或孤立干扰引起的 STAP 性能下降问题。 The results of the simulated experiments demonstrate that the proposed method can effectively alleviate the STAP performance degradation due to the interference target, discrete terrain clutter or isolation interference, compared with the traditional statistical STAP methods.
23928 该文基于绝对值型和指数型势函数，构建了更一般的指数型单稳势函数，深入研究了Levy噪声驱动的指数型单稳系统，并总结出不同特征指数a和不同对称参数b下，指数型系统参数l和，b  Levy噪声强度系数D对指数系统共振输出的作用规律。 Based on the absolute and exponential monostable potential, a generalized exponential type single-well potential function is constructed. The laws for the resonant output of monostable system governed by l and ,bD of  Levy noise are explored under different characteristic index a and symmetry parameter b of  Levy noise.
23929 研究表明：在不同Levy噪声驱动下，通过调节参数l和b均可诱导随机共振(SR)，且当b(或l)的取值越大时，产生较好随机共振效果l(或b)的区间越大，从而改善传统SR系统由于参数选择不当造成随机共振效果不佳的问题。 The results show that the stochastic resonance phenomenon can be induced by adjusting the exponential type parameters l and b under anyaor b of Levy noise. The larger b (or l) is, the wider parameter interval of l (or b) can induce SR (Stochastic Resonance). The ESR (Exponential SR) system can solve the problem that the traditional system can not achieve SR due to the improper selection of parameters.
23930 此外，通过调节噪声强度系数D也能产生随机共振，且较好随机共振区间不随a或b变化； The interval of Dof Levy noise, which induces good stochastic resonance, does not change withaor b.
23931 最后将指数型单稳系统应用于轴承故障检测，效果明显优于传统双稳系统。 At last, the proposed exponential type monostable is applicated to detect bearing fault signals, which achieves better performance compared with the traditional bisabled system.
23932 异构签密方案能够为不同安全域之间的数据通信提供机密性和认证性。 Heterogeneous signcryption scheme can ensure the confidentiality and the authentication for data communication between different security domains.
23933 分析现有的异构签密方案，都是在随机预言模型下可证安全的。 Some existing heterogeneous signcryption schemes are analyzed to be secure in the random oracle model.
23934 基于此，该文提出一个在标准模型下从基于身份的密码到传统公钥设施的签密方案，利用计算 Diffie-Hellman 问题和判定双线性 Diffie-Hellman 问题的困难性，对该方案的机密性和不可伪造性进行了证明。 Based on this problem, an Identity-Based Cryptography (IBC) to Public Key Infrastructure (PKI) signcryption scheme is proposed. The proposed scheme has the confidentiality and the unforgeability under the Computational Diffie-Hellman (CDH) problem and the Decisional Bilinear Diffie-HellmanB (DBDH) problem.
