Non-Cooperative, Non-Line of Sight Geolocation of Radio Emitters

Estimating the location of radio emitters in multipath environments is known to be challenging, particularly when no Line of Sight (LOS) path is present. We propose novel non-cooperate Maximum Likelihood (ML) location estimator for use in dense urban environments which uniquely exploits the scattering environment geometry in order to mitigate the need for LOS paths. A simple scattering model is used to assess the performance of the algorithm. Simulation results are included demonstrating a mean location error of 89 m.
