Abstract :
In practical applications, multipath is the dominant error source for parameter estimation. In this paper, a far-field source and its near-field multipaths are considered. Far-field source azimuth and elevation angles are estimated using multipath calibration. A near-to-far field transformation is proposed for near-field source localization where azimuth and range parameters are estimated. Proposed method is evaluated using close-to-real world data generated by a commercial numerical electromagnetic tool. It is shown that parameters can be estimated effectively showing the potential of the proposed approach for practical applications.
