Abstract

An apparatus a transmitter section, a receiver section, and a processing module. The transmitter section transmits a plurality of high carrier frequency beamformed signals in a loop manner until a desired number of signals has been transmitted. The receiver section receives the plurality of high carrier frequency beamformed signals and determines reception properties of the plurality of high carrier frequency beamformed signals. The processing module determines at least one of: reflection, absorption, refraction, and pass through based on the reception properties. The processing module then distinguishes an animate entity from an inanimate entity based on the at least one of the reflection, absorption, refraction, and pass through. The processing module then determines position of the animate entity within a given physical area.
