Publication number: 20210160001Abstract: Methods, systems, and devices for tampering detection in phase based ranging are described. A device may engage in two-tone phase based ranging. For example, the device may transmit a composite signal that includes a first carrier at a first frequency and a second carrier at a second frequency. The device may receive a third carrier at the first frequency and measure its phase. The device may determine a phase sum associated with the first frequency based on the measured phase of the third carrier and a measured phase of the first carrier. The device may compare the phase sum with a reference value and determine whether tampering with the phase based ranging has occurred based on the comparison.Type: ApplicationFiled: November 26, 2019Publication date: May 27, 2021Inventors: Paul Dominic HISCOCK, Thomas ALLAN
