Abstract

This work derives new non-asymptotic and asymptotic Cramér-Rao lower bounds (CRB) for the estimation of multiple pure-tone incident signals' amplitudes, azimuth-elevation arrival-angles, polarization parameters, and frequencies, based on data observed from one dipole triad (composed of three spatially collocated but orthogonally oriented electrically short dipoles) or one loop-triad (composed of three spatially collocated but orthogonally oriented magnetically small loops). The incident sources are pure-tones at distinct frequencies, in contrast to the existing electromagnetic antenna-array signal-estimation CRB literature's modeling of all sources to be at the same carrier-frequency.
