Abstract: A method may include receiving radar data from a plurality of TX-RX pairs (TRPs); generating a plurality of first ellipses representing a first portion of the received radar data; determining a blocking likelihood at a point of intersection between the plurality of first ellipses; generating a new or additional ellipse representing a second portion of the received radar data; and updating, based on generating the new or additional ellipse, the blocking likelihood at the point of intersection between the first plurality of ellipses.

Abstract: The present disclosure generally relates to localization and, more particularly, to remote localization and radio-frequency identification using a combination of structural and antenna mode scattering responses. A method and system include receiving location data of an object from a plurality of transmitter-reader pairs (TRPs); generating a plurality of first ellipses representing the received location data; determining blocking likelihoods at points of intersection between the plurality of first ellipses; generating additional ellipses representing additional location data received from additional TRPs; and updating the blocking likelihoods at points of intersection between the plurality of first ellipses and the additional ellipses.
