摘　　要：本文讨论了H．Kimura和Y．Honoki提出的基于降维处理的高分辨率二维谱估计算法，并通过引入自适应定阶和“相关阵”正定性修正方法，对它进行了改进。经模拟分析表明，改进后的算法具有更高的计算效率和良好的性能。A high resolution 2-D spectral estimation algorithm by reducing dimension, proposed by H.Kimura and Y.Honoki, is discussed in this paper. Some algorithms about adaptive determination of the model order and positive definite modificaton of the autocorrelation matrix are suggested to improve the 2-D spectral estimation. Simulary experiments show that the improved algorithm has more computational effectivenesss and higher resolution.
