Unlike the previous method, however, the proposed algorithm obtains the new transformed matrix by taking the conjugate operation to the forward and backward spatial smoothing covariance matrix of the received data, so that the modified covariance differencing matrix which is a Hermitian matrix of zero real part can lower the computation load effectively during the eigenvalue decomposition.

不同于以前的算法，提出的算法通过对接收数据的前后向空间平滑协方差矩阵进行共轭运算得到新的变换矩阵，因此修正后的协方差差分矩阵是个实部为零的厄米特矩阵，从而有效地降低了特征分解过程的计算量。

The using of the technologies of DOA in the orientation estimating of interference is discussed, then an evolutive ESPRIT algorithm is put forward which avoids the eigendecomposition and is easily achieved. To the MUSIC algorithm, an easy eigendecomposition algorithm for Hermitian matrix is presented. It breaks away form the complex matrix decomposition such as QR algorithm. Basing on the whole matrix, the algorithm makes use of the multiplication operation of matrix and vector, which attains simpleness and is fit for DSP. In the field of DOA estimating of correlation interferences, spatial smoothing algorithm consumes too many array units.

讨论了DOA技术在干扰源方位估计中的应用，提出了一种ESPRIT演变算法，该算法避开了特征值分解，实现简便；在MUSIC算法的实现中提出了一个Hermitian矩阵特征值分解算法，该算法摆脱了复杂矩阵分解，从矩阵整体出发，主要的运算是矩阵与矢量的乘运算，算法简单，非常适合DSP芯片实现；在相关源的DOA估计中，空间平滑技术使阵元的损失非常大，本文提出了一种进一步降低阵元消耗的平滑技术—随机空间增益法，其在运算量上的增加很小，但对于相干源的去相关确是有效的。

As the basement to integrate multi-scale spatiotemporal data, the object evolution model can retain the characteristic of the data with different temporal-scale or different spatial-scale, and reflect the temporal changes especially the heteromorphic changes, and the causalities within the evolving process.

本文通过对时空对象变化过程的分析，指出对象进化的结果不仅是特征的变化，还包括机制的变化，其直接动力是对象行为，其根本原因是其内在机制，时空事件起着对象间信息通道的作用，据此提出对象进化模型，该模型可作为多尺度时空数据集成的结构性基础，在反映时空现象的演变过程，特别是异构演变过程，以及在这个过程中产生的因果关系的同时，还可以保留时空数据的不同时间尺度和空间尺度特点，从而达到增加时空数据库的信息量的目的。
