Anti-radar-reconnaissance spherical reflector capable of imitating landform and ground object

Provided is an anti-radar-reconnaissance spherical reflector capable of imitating a landform and a ground object. The spherical reflector comprises a reflector disposed inside a spherical housing. The reflector comprises two circular plates with equal diameters, and at least one sector plate with a 90-degree central angle; the straight edge length of the sector plate is smaller than the radius of each circular plate; the two circular plates are vertically attached to each other along a radius direction; four cavities with equal volumes are formed among the two circular plates and the housing; the sector plate is disposed inside any one cavity; the sector plate is respectively vertically attached to the plate surfaces, which are disposed in a corresponding same cavity, of the two circular plates so that at least two reflection spaces are formed among the sector plate, the two circular plates and the housing; the sector plate and the surfaces of the two circular plates are provided with metal layers; and the su
