1. A method for remotely measuring pressure of a fluid in a container implemented by one or more computing devices, the method comprising:
determining a spatial location of first and second resonant radiofrequency antenna elements located on a radiofrequency identification (RFID) tag located in the container holding the fluid such that the RFID tag is immersed in the fluid, the first radiofrequency antenna element positioned in fixed position on the RFID tag and the second resonant radiofrequency antenna element positioned on a deformable element configured to be deformed in at least one dimension based on pressure from the fluid, from a radar image generated based on reflected radiofrequency beams from a scan area and re-radiated radiofrequency beams from the first and second resonant radiofrequency antenna elements located within the scan area resulting from the transmission of a radiofrequency beam to the scan area; and
determining, based on the spatial location of the first and second resonant radiofrequency antenna elements, a pressure value for the fluid.
