Abstract :
A multistatic microwave frequency-modulated continuous-wave (FMCW) radar system used to localize a remote Tag in an Indoor Environment is described. The frequency information extracted from the FMCW data can be processed for the range and the angle-of-arrival (AoA) estimations by computing the average frequency shifts over a fixed sweeping period of time by utilizing the DMTD (Dual Mixer Time Difference) technique. This allows to reduce the sweeping frequency range while maintaining the accuracy.
