摘要 基于特征值分解的高分辨率DOA估计算法,在理想阵列条件下,性能很好,但是对噪声扰动和系统误差都很敏感,噪声扰动和系统误差会严重恶化这一类算法的性能,使其分辨率下降。该文提出一种基于MUSIC算法的盲估计方法,它仅仅需要在阵列周围满足远场条件的地方布置一个RF信号源,不需要知道信号源的方位角,就可以精确估计阵列天线的通道误差。仿真结果证明,这种方法行之有效,而且效果比较理想。 The high-resolution eigenstructure-based DOA estimation methods, such as MUSIC algorithm, have an excellent performance in ideal cases. Their performance is susceptible to noise perturbation and array error and degrade significantly when array is with error. An blind calibration method MUSIC-based is present in this paper. It need only one RF signal generator placed in the far-field without knowledge of DOA of incidence signal. Computer simulations illustrate that the method is effective and the calibration result is perfect.
