基于分形方法的机载雷达云仿真

为了提高军事仿真训练的逼真程度，根据云的特性以及机载气象雷达上云的成像，提出了一种虚拟云的建模方法，应用分形技术中一种改进的逐次随机增加法进行云数据建模，并且选择适当的控制源曲面，在此控制源曲面基础上与分形生成的曲面进行加权融合，生成具有预定形状的云数据模型。最后将此数据模型按照一定的生成法则在相应点映射成颜色值，建立高度和颜色值的对应关系，可实现机载气象雷达屏幕云的成像仿真。

Simulation of Airborne Radar Cloud Based on the Fractal Theory

In order to improve the realistic military simulation training, a way of the modeling of a virtual cloud is put forward according to the characteristics of cloud and cloud on the Airborne Weather Radar imaging. Based on the fractal theory , an improved successive increase in random method to instruct cloud data modeling is chosen , and to select the appropriate locus of control surfaces. On the basis of the locus of control surfaces and the surface generated in the way of fractal this surface , weighted fusion to generate a predetermined shape of the cloud data model. Finally, according to the generating rules, make the data model map to color values in the corresponding points, and construct the corresponding relation between height and color values, so as to get the simulation of airborne weather radar screen cloud imaging .
