摘要： A method of determining a calibrated signal strength factor used for foreign object detection may be performed by a receiver positioned on top of a transmitter. The method may comprise measuring a first signal strength resulting from a digital ping initiated by the transmitter at a first position. The first position may be a best coupling position. A first Q-factor for the first position may be determined. The first Q-factor may be a reported Q-factor. A measurement of a second signal strength resulting from another digital ping may be initiated by the transmitter at a second position. A second Q-factor for the second position may be determined. The calibrated signal strength factor may be determined, based on the first signal strength, the second signal strength, the first Q-factor and the second Q-factor.
