PHASED-BASED RANGING

Abstract: a method of phase-based ranging between a first device and a second device, comprises receiving a plurality two-way phase-measurements between the first device and the second device performed at a plurality of frequencies; identifying a first measurement and a second measurement of said plurality of two-way phase measurements, said first measurement and said second measurement having been performed at a same frequency; calculating a relative speed between said first device and said second device based at least on said first measurement and said second measurement; doppler compensating a plurality of measurements of said plurality of two-way phase measurements based on the calculated relative speed; and calculating a distance between said first device and said second device based on the doppler compensated measurements, wherein said calculating comprises inputting the doppler compensated measurements to a neural network.
