| 摘要 | A calibration device, capable of calibrating a gain of a radiometer, includes an actuator and a micro-electromechanical-system (MEMS) unit. The actuator receives a calibration signal outputted from a control unit. The MEMS unit is coupled to the actuator, in which the actuator enables the MEMS unit to shield an antenna of the radiometer according to the calibration signal, such that the radiometer generates an environmental signal according to an equivalent radiant temperature received from the MEMS unit, and the control unit calibrates the gain of the radiometer according to the environmental signal. | ||
