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 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. The method includes processing each stream of the backscattered signals, using a digital signal processor, at a predetermined time to normalize the stream of backscattered signals to form a normalized signal corresponding to the stream of the backscattered signals and outputting a plurality of normalized signals numbered from 1 to N corresponding, respectively, to the plurality of back scattered signals, numbered from 1 to N.
