<p>Disclosed are a standing wave ratio detection method, device and base station, belonging to the field of mobile communications. The method includes: determining an equivalent parameter value S of a group of base station antenna ports at the frequency point in which a base station is interested; acquiring the power PFWD of a forward signal of the base station antenna port, the power PREV of a backward signal, and the phase difference ?f between the phases of the forward signal and the backward signal at this moment; and determining the standing wave ratio according to the S, PFWD, PREV and ?f. By way of the present invention, on the basis of the amplitude information about the forward and backward signals of the base station, the phase information affecting the standing wave ratio is calibrated using three different negative carriers, and the standing wave ratio of the base station is then calculated using the amplitude and phase information, improving the precision of the standing wave ratio, and thus improving the accuracy for detecting the connection state of the antenna feeder system.</p> |
