Owing to the small snapshots number problem, the correlation between the signal at interest frequency and the corresponding clutter-plus-noise must be considered in the proposed method. Comparison with the rank-deficient RCF spectral estimator, the proposed estimator has excellent estimation performance though its resolution is slightly worse. The numerical example is provided to demonstrate performance of the new spectral estimator. 关键词: Spectral analysis, adaptive estimation, array signal processing, matched filters (浏览全文) 发表日期: 2006年10月26日 同行评议:
(1) 提出了改进的谱估计方法,通过仿真验证,表明了方法的可行性。 (2) 对新方法缺乏论证,不能简单的用1个仿真实例得出结论说明算法性能先进,应该从理论上或者多方面的应用实例加以深入讨论。
