Models for the self‐ and cross‐correlation of orthogonal polarized quasi‐transverse incoherent scatter returns are presented. The models are used to estimate the F region plasma densities with dual‐polarization transverse‐beam incoherent scatter data collected at the Jicamarca Radio Observatory using a technique introduced by Kudeki et al. [2003]. The cross‐correlation model takes into account magneto‐ionic propagation effects associated with quasi‐transverse O‐ and X‐modes in an inhomogeneous ionosphere. The phase of the cross‐correlation provides the information to convert the measured power data into ionospheric density estimates via a least squares fitting procedure.
