Methods and systems for ultra-wideband (uwb) based subway personnel detection

A method for subway intrusion detection, the method comprising:

• transmitting 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 UWB signals within the area;
• processing 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.

A system for subway intrusion detection, the system comprising:

• one or more detection devices, wherein each detection device comprises:
• an ultra-wideband (UWB) based transceiver, configured for transmitting and receiving UWB signals;
• and
• wherein the one or more detection devices are 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 one or more detection devices;
• and
• detect based on the echoes of the transmitted UWB signals when an object is present within detection range of at least one of the one or more detection devices.
