Abstract
A method and data processing device for detecting and tracking objects in a space. The method includes transmitting an inquiry signal that traverses into the space, which is behind a physical barrier and is pre-configured with a plurality of radio frequency identification (RFID) tags. The method includes transmitting, via a RFID module, a second signal at a second frequency range. The method includes monitoring for a RFID response signal, which is a backscatter signal generated in response to the second signal impinging on the RFID tag and one or more objects in the space. The method includes identifying and extracting an interference reflection signal from the response signal to determine a presence of an unknown object. The method includes tracking the unknown object within the space and providing more specific position data of the unknown object within the space, to a display of an electronic device.
