A Modified Space-time Two-dimensional Highresolution Isolated-dimensional Estimate Method

介绍了一种应用在多普勒频率估计和 DOA估计分维处理情况下 ,利用数据矩阵及其共轭重构得到新的数据矩阵 ,借助数据矩阵奇异值分解方法和时域投影变换的空时二维超分辨方法。

A spacetime two dimensional high resolution method that applied to the situation of dopplershift frequency and directionofarrival(DOA) estimation are introduced This method use the data matrix and its conjugate reconstructional data matrix to create a new data matrix then based on the singular value decomposition(SVD) of the data matrix and projectiontransform in time domain to estimate the dopplershift frequency and DOA The result of computer simulation illustrate that the new method is robust and highresolutional
