Determining a location of a wireless transmitter
A method for determining a location of a wireless transmitter includes: receiving, at data processing hardware, receiver signals from corresponding receivers located within an observation area; estimating, by the data processing hardware, the location of the rogue transmitter; and reporting the estimated location of the rogue transmitter to a remote system in communication with the data processing hardware. Estimating the location of a rogue transmitter includes, for each receiver, determining a transmitter location contour about the receiver based on the corresponding at least one receiver signal and one or more propagation path loss functions and identifying an intersection of the transmitter location contours of the receivers as the estimated location of the rogue transmitter. Each propagation path loss function is based on terrain information corresponding to the observation area. The transmitter location contour defines a collection of candidate locations of the rogue transmitter relative to the receiver.
