24007 | 甚高频(VHF)和超高频(UHF)宽带 MIMO 雷达在实现目标高分辨与成像方面表现出巨大潜力,但也面临着工作频段拥塞和电磁信号干扰问题。 | Wideband MIMO radar exhibits great potential in achieving the goals of high resolution imaging, but it also suffers from the electromagnetic signal congestion and interference problems, especially for radar that works in Very High Frequency (VHF) and Ultra High Frequency (UHF) band. |
24008 | 针对这一问题,该文提出一种基于循环迭代的宽带 MIMO 雷达正交稀疏频谱波形设计方法。 | To solve this problem, a cyclic iterative method for designing orthogonal sparse frequency waveforms is proposed. |
24009 | 首先,将期望频谱矩阵作为待优化的辅助变量,综合考虑最小化发射波形频谱与期望频谱之间的均方误差以及积分旁瓣电平为目标函数,以发射波形恒模和期望频谱幅度满足上、下界约束为条件建立优化模型; | Firstly, the desired spectrum is used as an auxiliary variable, and a new objective function is constructed based on both the mean square error of the spectrum of transmitting waveform with the desired one and the integration side-lobe levels. The optimization model is established under the constraint that the waveform is constant envelope meanwhile the spectrum magnitude lies between the pre-established upper and lower bounds. |

24013 | 该算法利用信号分离评价指标来构造函数实现步长和动量因子的自适应调整,然后将构造函数代入盲分离算法中并引入自适应动量项。 | A function is constructed by signal separation evaluation index, which adaptively updates the step size and momentum factor, then substitutes the obtained variable step-size function into blind source separation algorithm and introduces the adaptive momentum item. |
24014 | 区别于大多数算法不对混合矩阵进行估计的问题,该算法用变步长函数迭代估计出混合矩阵,从而得到全局矩阵和估计评价指标,以此迭代更新步长和动量因子,最终得出分离矩阵。 | Different from most algorithms which can not estimate the mixing matrix, the proposed algorithm estimates iteratively the mixing matrix by the variable step function, then the global matrix and the estimated evaluation can be obtained on which step and momentum factor are iteratively updated. Finally, the separation matrix is obtained. |
