| 摘 要： | 基于阵列协方差矩阵特征分解的超分辨率测向技术，在天线阵各通道特性不一致时，其性能会急剧下降。本文提出了一种基于中频采样正交滤波技术的超分辨率测向新方法，该方法可以较好地保证通道的一致性和显著提高测向性能，计算机模拟证实了其有效性。

| Abstract: | For the eigenstructure based superresolution direction finding technique, uncertainties of array sensor gain and phase degrade severely its performance. In this paper, we present a new method for superresolution direction finding based on MF sampling and orthogonal filtering technique. The method can keep the array sensor gain and phase certain and improve obviously direction finding performance. Computer simulations have shown the effectiveness of the method. |
