摘要： A detection device with a calibration function is configured to detect an object. The detection device includes an antenna element, a transmission line, a detection circuit, and a processor. The transmission line is coupled to the antenna element. The detection circuit is coupled to the transmission line. The detection circuit performs a detection process, so as to obtain an estimated distance between the antenna element and the object. The processor is coupled to the detection circuit. The processor calculates the calibrated distance by subtracting the error distance from the estimated distance.
