Using numerical model of on-board antenna array efficacy of direction finding methods for ionosphere waves consisting of multiple beams with complex polarization was investigated. Finding-direction results was comparing for following methods: Bartlett, polarization independent modification of Bartlett; two kinds of polarization independent MUSIC, polarization independent multiple beams least-squares method. High efficacy of direction - finding of ionosphere waves was proved in the case of employing the electrodynamics modeling results.
