19865 该方案结合视频流的特征采用适应多播的RLNC，相较于传统RLNC计算复杂度降低。 The characteristics of the video stream and RLNC adapted to multicast are combined in this scheme. Compared with the traditionalRLNC, the computation complexity of this scheme is reduced.
19866 经过初始传输后，在后续数据恢复阶段，综合考虑数据包剩余传输时隙，选取目的节点增益最大传输方式，最大化数据传输。 After the initial transmission, the transmission slots left of the data packet are comprehensively considered in the subsequent data recovery phase, and the maximum transmission node of the destination node gain is selected to maximize data transmission.
19867 同时，各中继节点根据接收情况，构建各自解码概率值，并以此为依据确定调度优先级并完成转发，自适应调整各节点传输，有效减少对反馈信息的依赖。 At the same time, the decoding probability is available according to the different receiving situations in each relay node. According to the decoding probability value, the scheduling priority is determined, and the forwarding is completed. The transmission of each node is adaptively adjusted, and the feedback information is effectively reduced.
19868 仿真结果表明该方案与完全反馈方案性能十分接近，且在减小计算复杂度和降低对反馈信息依赖同时保证了较好的性能。 The simulation results show that the performance of this scheme is approached to the full-feedback scheme, with better performance in the reducing computational complexity and the decreasing feedback dependence.
19869 通常空间自旋目标的3维(3D)重构都是通过对散射点轨迹进行矩阵分解的方法得到的，散射点轨迹是从雷达序列图提取并关联得到的。 Generally speaking, Three Dimension (3D) imaging of spinning space target is obtained byperforming matrix factorization method on the scattering trajectories obtained from sequential radar images.
19870 由于散射点提取与关联误差的存在，3D重构会出现精度下降，甚至失败的问题。 Because of the errors of scattering center extraction and association, the 3D reconstruction accurate is reducedor even fail.
19871 另一方面，转台目标的散射点轨迹符合圆属性，这与几何投影理论认为散射点投影轨迹的椭圆属性相违背。 In addition, the scattering center trajectory from turntable target consists with circle nature, which is inconsistent with the elliptic property of the scattering center trajectory obtained by optical geometry projection.
19872 为解决以上问题，该文提出了基于短时的空间目标3D重构算法。 To tackle these problems, this paper proposes a short time 3D reconstruction method of space target.
19873 首先对提取的散射点轨迹进行2维圆属性拟合，使其轨迹光滑，更接近理论曲线。 Firstly, the retrieved trajectory is fitted with 2D circular nature to make the trajectory smooth and closer to the theoretical curve.
19874 然后采用多视角的方法估计雷达视角(LOS)，通过乘以雷达视角构成的系数，将圆属性轨迹曲线转变成椭圆属性轨迹曲线。 Then the radar Line Of Sight (LOS) is estimated by multiple views and the circular curve is converted into elliptical curve by multiplying the coefficients calculated by the LOS.
