| 8944 | 针对任务期间备件最终修复概率小于1、备件处于非稳态需求时传统完全可修件库存策略不合理的问题,扩展可修复备件多级管理(multi-echelon technique for recoverable item control,METRIC)理论,建立使用现场和后方基地两级SRU串件拼修对策下不完全修复件两级两层时变可用度评估模型。 | For spare parts during the final task repair probability is less than 1, the spare parts in the unsteady demand the traditional problem of the unreasonable fully repairable parts inventory strategy, expand repairable spares multi-level management (multi - echelon technique for recoverable item control, METRIC) theory, using the site and the rear base two-stage SRU string of cannibalization countermeasures under incomplete repair parts two levels of two layer time-varying availability assessment model. |
| 8945 | 列举案例对比分析串件拼修对策前后装备可用度变化,分析结果表明,串件拼修能一定程度上提高装备可用度,对装备可用度提高程度与LRU最终修复概率和初始备件携带数量有关。 | Enumerated case analysis of string a cannibalization countermeasures equipment availability before and after the change, the analysis results show that the string of a spell to a certain extent, improve equipment availability, to improve equipment availability and LRU eventually fix probability and the initial spare parts number to carry on. |
| 8946 | 最后,采用蒙特卡罗仿真方法对串件拼修对策下的备件保障模型进行了验证,仿真结果与解析结果误差在2%以内。 | Finally, the monte carlo simulation method is adopted to string of cannibalization countermeasures of spare parts under guarantee model is verified, the simulation and the result of parsing error within 2%. |
| 8947 | 针对地球同步轨道卫星发射-低轨道卫星接收的新体制双站合成孔径雷达(geosynchronous-earthorbit-low-earth-orbit bistatic synthetic aperture radar,GEO-LEO BiSAR)具有收发平台轨道差异大、空间大尺度异构等特点,对地面分辨特性和轨道构型进行了分析。 | For a satellite launch geosynchronous orbit - low orbit satellite receiving a new system of double stand synthetic aperture radar (geosynchronous earthorbit - low - earth - orbit bistatic synthetic aperture radar, GEO - LEO BiSAR) has a large difference of sending and receiving platform orbit, space, large scale and heterogeneous characteristics, analyses the characteristics of ground resolution and orbital configuration. |
| 8948 | 文中从收发平台的空间几何关系出发,深入分析了地面二维分辨率和分辨率方向角等性能,给出在不同观测模式下的构型约束规律,并规划了轨道构型设计方案。 | In this paper, starting from the spatial geometric relationships of sending and receiving platform, in-depth analysis of the two-dimensional direction Angle resolution and resolution on the ground, such as performance, given in different observation mode configuration constraint rule, the orbit configuration design and planning. |
| 8949 | 仿真实验结果验证了理论分析的正确性。 | The simulation results validate the correctness of theoretical analysis. |
| 8950 | 对于机载非正侧阵雷达,杂波谱的距离空变性使得直接利用邻近单元数据估计的协方差矩阵与真实协方差矩阵不匹配,导致空时自适应杂波抑制性能下降。 | For airborne array radar is a side, the distance spectrum empty transgender makes direct use of adjacent unit data to estimate the covariance matrix and covariance matrix real do not match, resulting in a decline in space-time adaptive clutter suppression performance. |
| 8951 | 基于配准的补偿(registration-based compensation,RBC)方法通过时域平滑来估计空时谱,继而对地杂波的距离依赖性进行补偿,由于时域孔径损失使杂波谱峰值的估计精度受到限制。 | Based on the compensation of registration (registration - -based compensation, RBC) method through temporal smoothing to estimate the space-time spectrum, then to compensate the distance dependence of the ground clutter, aperture loss due to the time domain spectrum peak estimation precision is restricted. |
| 8952 | 针对这一问题,考虑到杂波空时谱的稀疏性,本文利用迭代自适应算法(iterative adaptive approach,IAA)进行空时谱估计,并重构各辅助距离单元协方差矩阵以实现杂波谱配准,称为IAA-RBC算法。 | In order to solve this problem, considering the sparse clutter space-time spectrum, this paper, by using iterative adaptive algorithm (iterative adaptive that IAA) for space-time spectrum estimate, and reconstruct the auxiliary unit distance of covariance matrix to achieve spectrum registration, called IAA - RBC algorithm. |
| 8953 | 由于该算法不存在孔径损失,杂波谱配准精度更高。 | Because the algorithm does not exist aperture, spectrum registration precision is higher. |
