Abstract
A method for imaging a room by a controller includes requesting a signal, indicative of a measurement of a parameter, from a sensor associated with a position and direction of a mobile platform in the room, wherein the measurement from the sensor includes background noise, distortions, and a foreground signal of interest, in response to the mobile platform reaching a new position, requesting a second measurement of the parameter from the sensor associated with the new position of the mobile platform, spatially aggregating the signal from the sensor and associated position and direction to create an energy map via spatio-dynamic beamforming, wherein the background noise and distortions are reduced, by spatially averaging beamformed information acquired across multiple locations to synthesize signals indicative of the foreground signal of interest, analyzing the energy map to identify a state of an apparatus in the room, and outputting a foreground beamformed image.
