Abstract
A mobile platform for calibrated data acquisition includes a transceiver within the mobile platform, a locomotion unit configured to move the mobile platform within an area, a sensor coupled with the locomotion unit and configured to output a signal, and a controller that is configured to request a measurement of a parameter from the sensor, remove from the measurement, background noise associated with the mobile platform, thereby focusing the measurement to foreground noise, in response to the mobile platform reaching a new position and direction, request a second measurement of the parameter from the sensor, remove from the second measurement, background noise associated with the mobile platform at the new position, aggregate the signal from the sensor and associated position and direction to create an energy map via spatio-dynamic beamforming, and analyzing the energy map to identify a state of an apparatus in the area.
