In this paper we present a parameter estimation problem for practical electromagnetic signals generated by dipóle antennas positioned close to a receiving antenna of uniform circular array (UCA). The positions (direction of arrival and range) and the radiation characteristics of emitting sources are being estimated using super resolution techniques. We also estimate the time difference of arrival (TDOA) to calculate range by using generalized cross correlation of eigenvectors in the signal sub-space. The technique discussed here may be generalized to define a methodology to localize and characterize the radar imaging techniques and may be applicable to the separation of dielectric layers by reflecting signals.
