Patent ID: 6927725

Claim:
A calibration system for calibrating a radar system, the radar system having a detection zone and being adapted to determine a sensed position at a sensed time of a target in the detection zone, the system comprising: a calibration target having a non-augmented radar cross-section, the calibration target comprising a UAV having a position device and a signal augmentation device, the position device being adapted to determine an actual position of the UAV at an given time, the signal augmentation device being adapted to augment the radar cross-section of the target, and a calibration device in communication with the calibration target and adapted to receive the actual position from the position device of the calibration target, the calibration device being further in communication with the radar system and adapted to receive the sensed position of the target from the radar system, the calibration device being further adapted to detect a system error representing the difference between the actual position and the sensed position and provide the system error to the radar system.
