array output meaning in English
组合输出
Examples
- Byte array output stream class
字节数组输出流类 - The approach extends the parallel factor ( parafac ) analysis model from the common data - domain and subspace multiple invariance sensor array ( mi - sap ) formulations to the cumulant one , and forms three - way arrays by using the cumulant matrices got from array outputs , and analyzes the uniqueness of low - rank decomposition of the three - way arrays , then jointly estimates the ranges , frequencies and doas from the matrices via low - rank decomposition
该算法将通常在数据和子空间域应用的平行因子分析模型扩展至高阶累积量域，利用阵元输出计算的高阶累积量矩阵构造三面阵，分析了该三面阵低秩分解的唯一性，并从分解得到的多个矩阵中联合估计信源距离、频率及到达角。 - Under ideal conditions , adaptive array signal processing methods can get excellent performance and adaptive beamformers provide an improvement in array output signal - to - interference - plus - noise - ratio ( sinr ) in comparison with conventional beamforming . in practical operating circumstances , the performance of adaptive array signal processing methods degrade extremely due to existing errors
但是，在实际系统中总存在有误差，包括自适应训练样本有限次快拍引起的协方差矩阵的估计误差和各种系统误差，误差使得实际阵列流形与理想阵列流形存在差异，这时自适应阵列信号处理的性能会急剧下降。 - At first some modification is made in conventional beam forming of frequency domain , namely to estimate doa by arrays outputs on compensated spacial frequency points of echoes . then the cwt is utilized to signal processing in space - frequency domain for estimation of doa , and the corresponding modification is also made . in the dissertation , the computer simulations of doa estimation for both narrow - band and wide - band echoes are given , so do the necessary comparison among several methods and crb
首先在传统的频域波束形成算法的基础上，提出对宽带信号的频率补偿，也即对宽带回波信号的各空间频率根据时间频率的差异进行相应补偿，然后对各阵元输出求和来得到方位估计；其次将连续小波变换引入到空间?频率处理中，从而完成对目标方位的估计，并进行了相应地补偿。
