Claim 19:
20. A system for subway intrusion detection, the system comprising:
a plurality of detection devices,
wherein each detection device comprises an ultra-wideband (UWB) based transceiver, configured for transmitting and receiving UWB signals; and
wherein each detection device is configured for:
deployment within a subway tunnel; and
transmitting UWB signals into an area within the subway tunnel, the area comprising one or more tracks traversed by a train in the subway tunnel; and

one or more circuits configured to:
process received UWB signals, the processing comprising determining received UWB signals corresponding to echoes of transmitted UWB signals transmitted by the detection device; and
detect 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 is set or adjusted to ensure full detection coverage in the at least one section of the one or more tracks.
