Claim 10:
11. A method for subway intrusion detection, the method comprising:
transmitting, by a plurality of detection devices, UWB signals into an area within a subway tunnel, the area comprising one or more tracks traversed by a train in the subway tunnel;
receiving, by the plurality of detection devices, received UWB signals within the area;
processing the received UWB signals, the processing comprising determining received UWB signals corresponding to echoes of the transmitted UWB signals; and
detecting based on the echoes of the transmitted UWB signals when an object is present within the area, wherein at least a portion of the detecting is done automatically, the automatic detecting comprising:
automatically selecting one or more detection devices of the plurality of detection devices, and
automatically analyzing the echoes of the transmitted UWB signals obtained by the one or more detection devices based on a detection criteria that comprise, at least, movement of a minimum sized cross-sectional area;

wherein:
the plurality of detection devices are deployed near at least one section of the one or more tracks, and
deployment of the plurality of detection devices comprises setting or adjusting the deployment to ensure full detection coverage in the at least one section of the one or more tracks.
