Abstract:
In the literature of direct blind geolocalization algorithms, two algorithms are mainly concurrent: DPD and LOST. The first one appears to be very sensitive to the spectral contents and the second, although presenting wide scope of scenarii with better performance than DPD, does not exploit the TDoA. This last algorithm could therefore be again improved. The purpose of this paper is to propose a new algorithm LOST-FIND which exploits (for non monochromatic sources) the structured TDoA between stations thanks to a spectral estimation of sources. The proposed algorithm is an iterative extension of LOST algorithm initially designed for monochromatic sources. Simulations confirm the expected improvements versus DPD and LOST.
