Abstract
A method of wireless device location determination includes defining a region of interest comprising a plurality of sensors. A reference frame and a grid comprises a plurality of simulation points with locations based on a coordinate system associated with the region of interest. Location coordinates for the plurality of sensors are established. A plurality of simulated wireless signal strengths is determined for each simulation point. A plurality of simulated signal strength matrix is generated using the plurality of simulated wireless signal strengths. A composite matrix is generated based on the plurality of simulated signal strength matrices. Wireless signal strength is measured at each of the plurality of sensors based. A measured wireless signal strength vector is then generated based on the measured wireless signal strength. A location of the intrusive device is then determined based on the measured wireless signal strength vector and the composite matrix.
