三维散射 meaning in English
three-dimensional scattering
Examples
- A study on hemispherical canyon p wave dispersion
波的三维散射 - Nodal fem / bi is employed for two - dimensional problems , and vector fem / bi for three - dimensional problems
在二维和三维散射问题中，分别应用二维结点fem bi混合方法和三维矢量fem bi混合方法。 - First the 3 - d scattering model of the targets is built based on the theory of radar target scattering center in the optics region and measure data , then by comparing the profiles of actual target with the profiles of model target , the two most resemble profiles are regarded as the target recognition result
目标识别时，用目标的实测距离像与数据库中所有目标的三维散射模型在任意姿态角上的投影形成的距离像进行匹配，取相关性最强的目标类型作为识别输出结果。 - This method can save the space of memory and reduce the computation time . because only the parameters of scattering centers are stored and genetic algorithm is used to search for aspect angle , the method is very suitable for the employment in real - time and restrictive environment . in chapter 3 , the architecture of mmw seeker is studied
该方法以目标多散射中心理论为基础，只需要存贮目标的三维散射模型参数，需要的存贮量较少；与常规的全姿态角匹配识别方法比较，基于目标散射模型的匹配识别方法，由于利用了遗传算法的全局寻优能力，计算量较小。 - On the base of mathematical domain decomposition method ( ddm ) , this paper investigates systematically the quasi - static problems based on laplace equation , the transmission problems in waveguide based helmholtz equation and the three - dimensional scattering and radiation problems based on maxwell equations . the theoretical system is built for the further exploration of ddm in electromagnetic problems
本文在区域分解法已有的数学基础上，从基于laplace方程的准静态问题，到基于helmholtz方程的波导传输问题以及基于maxwell方程的三维散射辐射问题，系统地探讨了该方法在电磁领域中的应用，为进一步扩展应用研究建立了理论体系。
