<p>A method and apparatus for detecting an intruder are disclosed. A method for detecting a motion using a multi-antennas sensor may comprise the steps of obtaining a first reception signal in response to a signal which is transmitted from the multi-antennas sensor; and calculating a relation matrix from the first reception signal, determining whether a value of the relation matrix is greater than an intrusion decision threshold, and determining whether there is a motion in a sensing area of the multi-antennas sensor. Therefore, the present invention can perform sensing actively depending on a change in a sensing environment.</p> |
