A three dimension polarization filtering algorithm is put forward to suppress the skywave interference in HF ground wave radar. The new technique can suppress the interference which can't be handled in a two dimension polarization filter. For the realization of algorithm and the adaptative fast varying interference, an instantaneous polarization filtering algorithm is given, which is very simple and can adapt the polarization states of interference at sampling speed.
