摘要：
A detection sensor (1) comprises a signal transmitter (10), configured to successively generate and transmit a detection signal (4), in a plurality of observation intervals, and a signal receiver (11), configured to receive a scatter signal (5). It comprises a plurality of frequency bins, resulting from a scattering of the detection signal (4), in the plurality of observation intervals. Moreover, the detection sensor (1) comprises an event generator (12), configured to compare a present scatter signal to a previous scatter signal, separately for each of the plurality of frequency bins, and generate an event for each frequency bin, in which the present scatter signal differs from the previous scatter signal by at least an event threshold amount.
