For the purpose of investigating influence of waves on the performance of eliminating glints reflected off wavy sea surface by polarization filtering, we viewed glints twinkled in glitter path using a simultaneous multi-channel polarization camera. By analyzing the recorded data, it is found that the waving of water surface do not make unlimited influence on polarization elimination performance. Then a semi-quantitative analysis method is introduced. Combing with simulation results, it is concluded that the influence level of waves on polarization elimination performance is determined by observation geometry primarily and then limited by receiver's field of view. When observation geometry is approach to the Brewster condition closer, polarization filtering will has batter performance which is represented by more decrease of intensity of glints and lower influence level of waves on reducing intensity of glints.
