RaySAR是一种能够产生SAR图像层的3D合成孔径雷达（SAR）模拟器 与详细的3D对象模型相关。 此外，它可以将3D位置和表面定位 相关点与反射雷达信号有关。(RaySAR is a 3D synthetic aperture radar (SAR) simulator which enables to generate SAR image layers related to detailed 3D object models. Moreover, it enables one to

RaySAR是一3D合成孔径雷达（SAR）仿真程序，基于matlab实现。(RaySAR is a 3D synthetic aperture radar (SAR) simulator which enables to generate SAR image layers related to detailed 3D object models. Moreover, it enables one to localize the 3D positions and surface interse

简单判断线与面的关系以及面与面的关系，并且有开窗功能，保留相交线(A simple judgement of the relationship between line and surface, as well as the relationship between the surface and the surface, and the function of windowing, preserving the intersection line.)

Mall-Kendall以气候、下垫面一致为前提，要求序列随机独立且同分布，用于突变点的识别。 UFk为一条随k变化的曲线，当n增加时，UFk很快趋于标准正态分布。 假设H0成立。给定显著性水平α，查算正态分布表得。当|UFk|＜时，接受原假设，即趋势不显著；反之，拒绝原假设，即趋势显著。 在坐标轴上绘制两条曲线，若相交，则交点为突变点。这就是Mall-Kendall法。(Mall-Kendall to climate and underlying surface consistent i
