Certainly with a number of fixed stations and a head echo Doppler shift that passes through zero Hz there are ways of determining the trajectory of the meteoroid. With good timing of the zero Doppler then velocity can be obtained.
The idea of using polarisation is interesting and I will think about it. The alignment of the meteoroid trajectory will feature in the signal received but also the orientation of the antenna in xyz cooridinates I think.
