The present application provides a method for sensing a target. The method comprises: receiving echo signals from a first moment to a second moment; calculating, on the basis of the received echo signals, a feature value corresponding to each target moment to obtain a feature value sequence, wherein the feature value sequence consists of feature values corresponding to a plurality of target moments sorted in chronological order, and the target moments are moments between the first moment and the second moment; and the process of calculating the feature value corresponding to the target moment comprises: obtaining, on the basis of a plurality of target echo signals received in a sub-time period before the target moment, target spectrum data respectively corresponding to the plurality of target echo signals, the sub-time period comprising the target moment, and the target spectrum data being spectrum data corresponding to a frequency point of which a range value is less than a preset value; and obtaining, on th
