Abstract: In an example, the present invention provides a method for processing rf backscattered signals. The method includes generating a plurality of rf signals numbered from 1 to N, where N is an integer greater than 1, from, respectively, a plurality of rf sources numbered from 1 to N. In an example, each of the rf sources is an antenna. In an example, the method includes transferring the plurality of rf signals to a predetermined region of space. The method includes receiving a stream of back scattered signals derived from each of the rf signals numbered from 1 to N from the predetermined space, each stream of back scattered signals being one of a plurality of backscattered signals numbered 1 to N corresponding, respectively, to the plurality of rf sources numbered from 1 to N.

Abstract: In an example, the present technique includes a method for capturing information from a spatial region to monitor human activities and create a spatial map of the spatial region. In an example, the technique allows a user of a cell phone to move from one location to another location and be tracked using rf backscattering, and each location being identified by the user by communicating a label via a cell phone or other mobile device.
