五单元圆型天线阵干涉仪测向系统cexiang
针对五单元圆型天线阵干涉仪测向系统，分别对等基线和不等基线的结构和相位模糊进行了分析；通过对多基线测量数据的加权处理提高测向精度，提出了权系数的选择方法和测向信号处理算法，其中包括相位差估计、角度变换、解模糊和接收通道误差校正等；计算机仿真结果表明两种结构基线的测向精度非常接近，在全方位、超短波频段内的最大测向误差小于0.10。(eee)

说明： 图论算法
求SAP矩阵的基本思想是图的最短路的问题。
由于铁路的运输费用与线路的长度不是线性关系，必须对铁路网做一些预处理才能套用图的标准最短算法。
(SAP matrix graph theory algorithm for getting the basic idea is to map the shortest path problem. Since the railway transport costs and the length of line is not a linear relationship, we must do some preprocessing on the rail network to apply a standard graph algorithm shortest.)

The fusion of high-spectral/low-spatial resolution
multispectral and low-spectral/high-spatial resolution panchromatic
satellite images is a very useful technique in various
applications of remote sensing. Recently, some studies showed
that a wavelet-based image fusion method provides high quality
spectral content in fused images. However, most wavelet-based
methods yield fused results with spatial resolution that is less
than that obtained via the Brovey, IHS, and PCA fusion methods.
In this paper, we introduce a new method based on a curvelet
transform, which represents edges better than wavelets. Since
edges play a fundamental role in image representation, one
effective means to enhance spatial resolution is to enhance the
edges. The curvelet-based image fusion method provides richer
information in the spatial and spectral domains simultaneously.
We performed Landsat ETM+ image fusion and found that the
proposed method provides optimum fusion results.
