Radar calibration satellite

Radar calibration satellites are orbital objects of known shape and size used to calibrate ground-based radars.[1] Examples include the SURCAL series developed by the Naval Research Laboratory and RADCAL,[2] both of which used active transponders, and the passive Lincoln Calibration Sphere 1 developed by the MIT Lincoln Laboratory.
