laser radar cross section meaning in English
激光雷达截面积
Examples
- In the research realm of the target identify , an important topic is to minish the laser radar cross section of the space target for target stealth . the laser radar probes a target is based on the target under the laser , the space and time distribute characteristic of the strength ? polarization and phasic of the laser scattering etc . to identify a target
在目标识别研究领域有一个重要的课题是减小空间目标的激光雷达散射截面便于目标隐身。激光雷达探测目标是根据目标在激光照射下,激光散射的强度、偏振和相位等的空间和时间分布特征来识别目标,目标表面粗糙度是影响目标激光散射特性的重要影响因素。 - From the model study of the fractal random rough surface , we acquire one dimensional ? two dimensional fractal random rough surface model with fractal theory ; 2 . the calculation of the scattering field of light ; the establishment of the scattering light ’ intensity model , and the number calculation of the intensity distribute ; 3 . the study on the laser radar cross section of one - dimensional fractal rough surface target ; and the number calculation of the scattering intensity of two - dimensional fractal the rough surface target ; 4 . through shadowing effect , we analysis light scattering characteristic of fractal rough surface
