In accordance with a first aspect of the present disclosure, a system is provided for facilitating detecting an unauthorized access to an object, the system comprising: a plurality of ultra-wideband (UWB) communication nodes; a controller operatively coupled to said plurality of UWB communication nodes, wherein the controller is configured to: cause at least one of the UWB communication nodes to transmit one or more UWB messages to other UWB communication nodes of said plurality of UWB communication nodes; receive a channel impulse response (CIR) estimate and/or one or more parameters relating to said CIR output by the UWB communication nodes in response to receiving said UWB messages; analyze said CIR estimate and/or said parameters relating to the CIR to detect said unauthorized access to the object. In accordance with a second aspect of the present disclosure, a corresponding method is conceived for facilitating detecting an unauthorized access to an object. In accordance with a third aspect of the present disclosure, a computer program is provided for carrying out said method.
