Abstract
A radio frequency (RF) imaging device comprises an RF sensor assembly, a position sensor, a processor, and a memory. The RF sensor assembly receives an RF signal for capturing an RF image of a portion of a space behind a surface. The position sensor receives a plurality of signals respectively emitted by a plurality of position markers at known positions relative to the surface. The processor determines a plurality of angles at which the plurality of signals respectively arrive at the position sensor and determines, based on the plurality of angles and the known positions of the plurality of position markers, a position of the RF imaging device relative to the surface. The memory stores the RF image in association with the determined position of the RF imaging device. A time-of-flight or triangulation of signal data may be used for position determination.
