| 摘 要： | 本文提出了一种基于空间滤波预处理的阵处理方法,旨在提高现有谱估计方法的分辨力。此法大大地提高了有效的信噪比(SNR)和自相关矩阵的估计精度。文中将此法应用于单次快摄的阵处理。模拟结果表明,用新方法可得到比用现有谱估计方法更好的结果。

| Abstract: | A method based on spatial filter preprocessing is presented to enhancethe resolution of the existing spectrum estimation algorithms. The effective signal-to-noise ratio (SNR) and the accuracy of autocorrelation estimation are significantly improved through use of this method. The method is applied to array processing in the signal snapshot case. Simulation results are presented to illustrate the improved performance achieved by the new method as compared with that obtained by the other existing algorithms. |
