53778 | 采用正交频分复用线性调频信号(Orthogonal Frequency Division Multiplexing Linear Frequency Modulated Signal,OFDM-LFM)作为发射波形,通过匹配滤波完成耦合回波分离和脉冲压缩,然后在频域进行频移操作消除步进频的相位影响,利用信息熵估计距离对齐后的多节点回波相位差,随后构建相应的相位补偿函数,进而完成各节点回波的相位差异补偿,最终得到分布式MIMO雷达多节点回波信号的相参积累结果。 | Orthogonal frequency division multiplexing linear frequency modulated(OFDM-LFM) signal was used as emission waveforms. The signal separation of coupling echoes and pulse compression were completed by matched filtering. In order to eliminate the impact of step frequency, we took frequency shift operation in the frequency domain. Information entropy function of the range alignment echoes was used to estimate the phase parameters, then we constructed the phase compensated function to compensate the phase differences of multi-node echoes. Finally, We obtained the coherent accumulation result of distributed MIMO radar. |

53783 | 针对该问题,我们提出基于三维张量低秩先验的多帧视频图像盲去模糊模型。在模型中,首先将多帧连续图像按时序维堆叠成张量,显式地考虑多帧图像间的时空关系,同时利用张量低秩先验约束保留图像重要纹理结构信息。 | In this paper, we propose a low-rank prior deblurring model based on a three-dimensional tensor, we pile up the continuous images into a tensor according to the temporal dimension, and use the tensor low-rank prior constraint, which not only maintains the dominant texture structure information to estimate the blur kernel but also considers the spatiotemporal relationship among multiple frames. |
