The invention relates to a standing wave detection method, a standing wave detection device and a base station. The method comprises the following steps of: acquiring feedback signals which take baseband multi-tone signals as transmitting signals from a feedback channel of the base station; performing calibration processing on the feedback signals by using stored calibration data to acquiring reflection signals in the feedback signals, wherein the calibration data are respectively the baseband multi-tone signals acquired at a calibration point in the situations such as an open circuit, a short circuit and a matched load and corresponding feedback signals; and acquiring a standing wave detection value according to the transmitting signals and the reflection signals in the feedback signals.By taking the baseband multi-tone signals as the transmitting signals, namely baseband signals, used when in a detection, and receiving the feedback signals through the feedback channel, a time domain system transmission function is acquired by using the transmitting signals and the feedback signals so that a standing wave detection is more convenient. Simultaneously, the calibration processing is performed on the feedback signals by using the stored calibration data, so that the precision of the standing wave detection is improved.
