Abstract:
Here, we present a method of locating nearfield
electromagnetic sources by estimating the parameters
using the new C-SPRIT algorithm. A simple L-shape
received antenna array is used for locating the sources of
scattering signal from 3-D point of view where the distance
(range), azimuth and elevation angles are the parameters of
interest. The scattering sources are modeled as thin finite
dipole antennas that are located in the near-field of the
receiver array. The ranges of the sources are calculated
using the estimated time difference of arrival (TDOA) of
scattered signals. Generalized cross correlation among the
eigen vectors in the signal subspace is used for the estimation
of the TDOA.
