Summary:The present invention is a reflector used to calibrate an imaging radar mounted on an air vehicle or satellite, and includes a plurality of reflectors formed in a cylindrical or cylindrical shape to reflect electromagnetic waves transmitted from the imaging radar on the ground. The reflectors reflected waves with different reflection intensities so that the imaging radar can distinguish between reflected waves reflected from the reflectors and reflected waves reflected from other objects. The imaging radars are arranged spaced apart from each other at preset positions, and electromagnetic waves of the imaging radar can be reflected uniformly at various angles. 본 발명은 비행체 또는 인공위성에 탑재된 영상레이다를 보정하기 위해 사용하는 반사장치로서, 상기 영상레이다가 송출하는 전자파를 지상에서 반사하도록 원기둥 또는 원통 형태로 형성되는 복수개의 반사기를 포함하고, 상기 반사기들은, 상기 반사기들에서 반사되는 반사파와 다른 물체에서 반사되는 반사파를 상기 영상레이다가 구분할 수 있도록 서로 다른 반사세기로 반사파를 반사하고, 미리 설정된 위치에 서로 이격되어 배치되고, 영상레이다의 전자파를 다양한 각도에서 균일하게 반사할 수 있다.
