21346 针对多模传播引起的扩展多普勒杂波影响天波超视距雷达对低可探测慢速舰船目标检测性能的问题，该文在新一代多输入多输出天波超视距雷达系统下，利用双迭代最小方差无失真响应(MVDR)波束形成器抑制多模扩展多普勒杂波。 Spread Doppler Clutter (SDC) caused by multi-mode propagation restrains the detection performanceof Over-The-Horizon Radar (OTHR) for low detectable targets, such as slow ships. To solve this problem，abi-iterative Minimum Variance Distortionless Response (MVDR) beamformer is proposed to suppress multi-mode SDC for MIMO OTHR system.
21347 考虑到时间叉排线性调频连续波MIMO天波雷达和慢时间相位编码MIMO天波雷达在有限相干积累时间内的训练样本数有限，且训练样本中包含主选模式期望信号，该文利用阻塞矩阵进行数据预处理，减小训练样本中的主选模式期望信号影响，并将LN×1维“发射-接收”2维权矢量优化分解为L×1维发射权矢量和N×1维接收权矢量， As it is difficult to obtain the signal-free training data and enough sample support in MIMO-OTHR with time-staggered linear frequency modulated continuous wave or slow time phase-coded waveforms, the block matrix is used for data preprocessing to reduce the effect of expected signal component in the training data, then multi-mode SDC could be suppressed by the LN-variate MVDR beamformer which is restored through bi-iterative calculation with an L-variate transmit and an N-variate receive beamformer.
21348 通过双迭代计算恢复出的2维MVDR权矢量来抑制多模扩展多普勒杂波，减小了计算量和样本需求。 This algorithm improves the convergence of MVDR beamformer, while reducing the computational load and the requirement of sample support.
21349 理论分析和仿真验证了算法的有效性。 Theoretical analysis and simulation experiment arepresented to verify the effectiveness of this algorithm.
21350 利用矩阵特征值的特性，该文提出新的无可信中心的秘密共享方案。 By using the characteristic of matrix eigenvalues, this paper proposes a new secret sharing scheme without trusted center.
21351 该方案无需可信中心的参与，每个参与者提供相同的秘密份额(列向量)，在黑盒子中协同产生各自的秘密份额，从而避免可信中心的权威欺骗。 The scheme does not require a trusted center, and each participant provides the same secret share (column vector) and generates its own secret share in the black box, thus avoiding the authority deception of the trusted center.
21352 所有参与者提供的列向量组成一个可逆矩阵P，可逆矩阵P和对角矩阵生成一个矩阵M，并将该矩阵正交化的单位特征向量，作为子密钥分发给各参与者。 Reversible matrix P consisting of column vectors provided by all participants, and diagonal matrix  generate a matrix M. Then, the orthogonalized unit eigenvectors of thematrix M is distributed to each participant as a subkey.
21353 由于同一个集合的参与者所对应的特征值是相同的，该方案可以有效地防止成员之间的恶意欺诈行为。 Because the eigenvalues corresponding to the participants in the same set are the same, this scheme can effectively prevent malicious fraud among members.
21354 分析结果表明，该方案是可行的、安全的。 Analysis results show that the program is feasible and safe.
