By the use of the electromagnetic reflection information of targets and ground in database, the radar detection model can generate radar image dynamically.
基于目标和地面电磁反射特性数据库的信息和雷达探测模型,实现了雷达图像动态生成。
Like its Cousins radar and sonar, lidar (light detection and ranging), works by broadcasting electromagnetic waves towards a target and then building up a picture from the reflection.
与雷达和声纳技术相似,激光雷达(光探测和测距)的工作原理是通过向目标发射电磁波然后根据反射波构建图像。
With electromagnetic theory of light, We found that the polarization of the light kept the same when the reflection of incident light satisfied critical reflection or dual-quadrature reflection.
应用光波的电磁场理论严格地推导了当入射光满足“临界反射”或“双正交反射”条件时,光的偏振态在反射过程不会发生改变。
