55788 针对短相干积累时间(coherent integration time,CIT)引起的多普勒分辨率低,无法从强大海杂波中检测出舰船目标的问题,提出了基于高阶奇异值分解(higher order singular value decomposition,HOSVD)的海杂波抑制算法。 For short coherent accumulation time (coherent integration time, CIT) caused by doppler resolution is low, unable to detect the ship targets from the strong sea clutter problem, was proposed based on higher order singular value decomposition (who order singular value decomposition, HOSVD) of sea clutter suppression algorithm.
55789 首先利用相邻单元内海杂波的相干性,将毗邻距离单元和方位单元的多脉冲接收数据应用三阶张量表示,然后采用HOSVD方法求解三阶张量的海杂波子空间和目标子空间的投影矩阵,最后利用投影矩阵将三阶张量映射到目标子空间以抑制海杂波。 First using coherence of adjacent unit in the inland sea clutter, the adjacent to the distance and bearing units of multiple pulse data applications of third order tensor, said then HOSVD method is used to solve the third order tensor subspace of sea clutter and target subspace projection matrix, the use of projection matrix to the third order tensor is mapped to a target subspace to suppress sea clutter.
55790 该方法与现有子空间类海杂波抑制方法相比,提高了信干噪比(signal to clutter plus noise ratio,SCNR)和峰值旁瓣电平比(peak sidelobe level ratio,PSLR),解决了目标谱峰偏移问题。 The method with the existing subspace class than sea clutter suppression method, improves the drying ratio (signal to clutter plus noise thewire, SCNR) and peak sidelobe level than (peak sidelobe level thewire, PSLR), solve the problem of the target spectrum peak shift.

55792 为了使多粒度方法适用于不完备信息系统,在相似关系的基础上,提出了基于集值信息系统的多粒度粗糙集模型,包括乐观和悲观两种不同的形式,不仅分析了两种模型的基本性质以及它们之间度量的关系,而且研究了决策规则获取的方法。 In order to make more granularity method suitable for incomplete information system, on the basis of the similarity relation, was proposed based on multi-granularity rough set model of set-valued information system, including the optimistic and pessimistic are two different forms, not only analyzes the basic properties of two kinds of model and measure the relationship between them, and study the decision rule acquisition method.
55793 最后将基于集值信息系统的多粒度粗糙集应用于信息系统安全审计风险判断,为信息系统安全审计的有效判断提供决策支持。 Finally to multiple granularity rough set based on set-valued information system applied in information system security audit risk judgment, is the judgment of information system security audit provide decision support.
55794 传统均匀圆阵波达方向(direction of arrival,DOA)估计算法要求天线数目多于目标数量,易受阵列的通道不一致性影响。 Traditional DOA of uniform circular array (direction of concatenated, DOA) estimation algorithm for antenna number more than the target number, affect the inconsistency of channels is vulnerable to the array.
55795 针对此问题,引入阵列基线旋转这一思想对多目标进行测向。 Aiming at this problem, introduction of baseline array rotation direction finding the idea of multi-objective.
55796 通过旋转两天线阵列基线,并以固定的时间延迟对阵元的接收数据进行采样,相当于利用有限的两个阵元对目标进行多位置观测,增加了阵元的利用率,提高了DOA估计的测向精度。 Baseline by rotating the antenna array, and at a fixed time delay against yuan receives the data sampling, equivalent to utilize the limited two arrays to target for multi position observation, increase the utilization rate of the array elements, improve the direction-finding precision of the DOA estimation.
