发射阵列互耦校正
Mutual Coupling Calibration for Transmitting Array
-
摘要: 该文给出了发射阵列的误差模型和相应的预失真校正方法。根据发射阵列的特点，提出了基于单元方向图法和合成波束法来计算发射互耦矩阵。仿真结果验证了这两种方法的有效性，在有发射噪声时第二种方法的性能要比第一种的好。

Abstract: Error model and its corresponding pre-distortion calibration method for trans-mitting array are presented in this paper. According to the characteristics of transmitting array, element-pattern-based and synthesized-beam-based methods are proposed to calculate mutual coupling matrix in transmitting mode. Simulation results verify the effectiveness of present methods. The second method shows better performances than the first one for the case where the transmitting noises exist in the channels. -
