Abstract :
The meteor trail interference worsens the performance of the sky wave OTHR. The interference greatly reduce target detection capability. An approach based on Gabor coefficient and binary hypothesis to restrain the meteor trail interference is developed in this paper. The approach is used to process the real measurement data of a Chinese sky wave radar and show effectiveness.
