A multi-application-transceiver device, comprising: at least one radar transceiver comprising a radar imaging sensor configured to receive a reflected signal in response to an original signal sent by the at least one radar transceiver, the reflected signal being reflected from at least one target object wherein the radar transceiver operates at a frequency greater or equal to 1 GHz; a signal conversion unit configured to convert the reflected signal into digital format; a digital signal processor component configured to pre-process the converted reflected signal using an alterable rule engine with a received rule set to discriminate a change in state of the at least one target object against an earlier state of the at least one target object in the context of a particular monitoring application wherein the state in change of the at least one target object is caused by a dislocation of the at least one target object, or is caused by a cross-section change of the at least one target object; and a middleware component configured to communicate with at least one remote computing device wherein communicate includes: send the pre-processed signal to the remote computing device, and receive from the at least one remote computing device the rule set for the alterable rule engine wherein the received rule set defines an application specific setting for the at least one radar transceiver and for the digital signal processor component to enable the particular monitoring application. at least one radar transceiver comprising a radar imaging sensor configured to receive a reflected signal in response to an original signal sent by the at least one radar transceiver, the reflected signal being reflected from at least one target object wherein the radar transceiver operates at a frequency greater or equal to 1 GHz; a signal conversion unit configured to convert the reflected signal into digital format; a digital signal processor component configured to pre-process the converted reflected signal using an alterable rule engine with a received rule set to discriminate a change in state of the at least one target object against an earlier state of the at least one target object in the context of a particular monitoring application wherein the state in change of the at least one target object is caused by a dislocation of the at least one target object, or is caused by a cross-section change of the at least one target object; and a middleware component configured to communicate with at least one remote computing device wherein communicate includes: send the pre-processed signal to the remote computing device, and receive from the at least one remote computing device the rule set for the alterable rule engine wherein the received rule set defines an application specific setting for the at least one radar transceiver and for the digital signal processor component to enable the particular monitoring application. send the pre-processed signal to the remote computing device, and receive from the at least one remote computing device the rule set for the alterable rule engine wherein the received rule set defines an application specific setting for the at least one radar transceiver and for the digital signal processor component to enable the particular monitoring application.
