摘要

This paper proposes a new geo-location algorithm to improve the accuracy of the positioning estimation of an unknown radio transmitter. We utilize received signal strength difference (RSSD) and angle of arrival (AoA) with the factor graph (FG) technique, the so-called RSSD-AoA-FG algorithm, to attain higher positioning accuracy. With the proposed algorithm, we can not only estimate the location of an unknown radio transmitter and eliminate the error effect from heterogeneous radio transmitting devices but also avoid ignoring the important AoA information of the radio transmitter. The simulation results show that RSSD-AoA-FG algorithm can obtain the best positioning performance compared with the RSSD-FG and AoA-FG techniques.
