反射物体 meaning in English

reflecting object

Since the distance from any given radar to each of these reflective surfaces ( which may be as much as 50km , or 30 miles , away ) is known precisely , the time it takes a beam to get there and back is a measure of how much water vapour it contains
因为可以精确获取某一雷达到这些反射物体中的任一表面的距离（可能有50公里，即30英里远），人们便可以通过雷达波往返两地所需的时间测得反射物的水蒸气含量。
The unfocused hologram of lensless fourier holography are also discussed , and a way to revise the reconstruction image of unfocused hologram is presented . ( 2 ) the reconstruction of image plane hologram is analyzed by plane wave theory . the image plane holograms of transparent and opaque objects are also obtained by using fibers
( 2 )用角谱理论分析了像面全息图的再现过程，采用光纤传光分别拍摄了透射和反射物体的像面全息图，并利用频域法对全息图进行数值再现，得到了物体较清晰的再现像。
